Who is Teddi Mellencamp? The ‘Real Housewives of Beverly Hills’ cast introduce their new co-star (Exclusive)

There’s a new ‘Wife in town and her name is Teddi Mellencamp Arroyave.

Teddi joins the cast of The Real Housewives of Beverly Hills for season eight, starting Tuesday on Bravo. So, who is she? ET got the scoop on the new girl straight from her co-stars at the RHOBH season premiere party at the Doheny Room in Hollywood -- with a little help from superfan Sarah Paulson (check out the video above).

“The new girl, I think you may like her,” Erika Girardi teases. “Young, fresh, opinionated, but you know, you’ll like me better.”

“[She’s] John Mellencamp's daughter,” Lisa Rinna notes, “who is 36, who is a baby. OK, she's a baby, let's face it.”

Yes, Teddi is the youngest cast member and grew up the daughter of a music legend, but she didn’t spend her childhood anywhere near Hollywood. Teddi was born in Indiana, then raised in South Carolina. So, it actually came as a bit of a surprise to her famous dad that she wanted to enter the spotlight.

“He was like, ‘You know, hun? If it's gonna make you happy, do it,’” Teddi shares. “‘But all I can tell you is, be yourself.'”

A bunch of you have written asking me if the #hairgummies worked because my hair "looks longer" on my #snapchat recently. I have been avoiding writing my "review" because @sugarbearhair gummies taste absolutely delicious and I looked forward to taking them every morning so I truly wanted them to be working. 🙈🤷🏼‍♀️ Alas, even though they were the yummiest treat ever, I still only have about 11 hairs and it did not grow or get thicker after 60 days. My hair was/is "magically thicker and longer" as of two weeks ago bc @samantharobinsonhair_ put a sh*t ton of extensions in my head bc I couldn't take looking at my 11 hairs any longer. So there you have it...long and short of it. #sugarbearhair I love you for your taste, not your results. #laworkoutjunkie #momlife #mom #momproblems #thinninghair #longhair #extensions #thickhair #honest #healthy #happy #triedit #hair #blonde #losangeles #dotheywork #honestreviews

Dear #losangeles, this is my "in deep thought" face... 😂 But, honestly why can't I find #gym or #fitness studio that have a 6am class or that are even open on Saturday mornings??? @equinox and @lafitness don't open until 8am and @classpass doesn't show any classes before 7:15am? Anyone have any suggestions?! Please leave them in the comments section so others who like to get up early know as well. It's 2 dark to run outside at that time and I have to be on the road to @hitscoachella2017 by 7:15am! #laworkoutjunkie #help #workout #westhollywood #earlyriser #workoutclasses #wknd #healthy #happy #momlife #equestrian #classpass I wish I had a #treadmill or a @pelotoncycle at my house for mornings like this!!! #run #cycle #spin #barre #yoga #saturdaymorning

Last run of #2016! Worked out everyday while the fam I and I have been in #utah Thank you @whitidwell for taking me to hilarious #dance classes and for letting me use your #treadmill and to @tedwinator for watching the kiddos for an hour so I can fit in an hour #workout. #maketime #exerciseismytherapy #laworkoutjunkie #run #dance #cardio #behappy #behealthy #smile #laugh #family #fitmom #momlife #happywifehappylife #happynewyear
Sometimes just getting dressed to workout feels like a feat...so sore today but not gonna waste my fave @aloyoga pants... If you are struggle city this morning like me, make sure you put on your fave #leggings and GO!!! Off to drop the kiddos at camp and then to @risenation. #laworkoutjunkie @classpass #classpass #classpassambassador #noexcuses #soreAF #transformationtuesday #theclimb #fitmom #momlife #maketime #workout #fitspo #instafit #6daysaweek #aloyoga #losangeles
Even though we were out till 2am after #gunsnroses we still made it to @speedplayla for a great class at 9am! Today's class was awesome because it was a #partnerchallenge #competition. Sadly @tedwinator and I came in 2nd place so we didn't win the cute @reebok sneaks. 😢💁 #laworkoutjunkie @classpass #classpass #classpassla #classpassambassador #fitmom #fitcouple #momlife #fitspo #noexcuses #workout #workhardplayhard #motivateeachother #loveofmylife
Did you schedule out your week????Words can't express how run down I feel today. That being said, I still made it to @barrysbootcamp this morning and signed up for @risenation tomorrow at 6am. I will do a total of 6 workouts this week, just like I do every week. It's so easy to get wrapped up in reasons why not to do something. Yes, in this moment while my kids are napping I just want to collapse...BUT, I know planning out our week so I can workout, work, write, ride and still be be an active good mom, stepmom and wife is more beneficial long term. Once all the scheduling is done I will feel more at peace and know I have done all I can to be the best me I can be. #laworkoutjunkie @classpass #classpass #classpassambassador #planitout #momlife #fitmom #mom #workout #workhard #maketime #noexcuses #exercise #horses #liveactive #fitnessblogger #motivate #happy #healthy #love #6daysaweek #summer
@hot8yoga #hotyogasculpt w/ @corneliusjonesjr 3 things you need to know: 1) @ambernicolehay has been begging me to take this class for months and I thought she was just drinking the #hotyoga8 kool-aid but I was wrong. This class is amazing, super sweaty and the perfect way to start a #saturday. 2) Cornelius plays great music and keeps your heart rate up with challenging weighted cardio and yoga sculpt exercises. He also has a fun beat driven tone to his voice that lit a fire in me during class. 3)This class is super hot and packed to the brim so make sure you arrive early to get a good spot. @tedwinator may or may not have had to take a couple #childspose breaks during class bc it was so challenging. 😂 we loved every second of it. PS. They offer a free week of classes to any #losangeles resident. #laworkoutjunkie #yoga #hotyoga #cardio #workout #noexcuses #sweat #sweatitout #fitnessblogger #fitmom #fitfriends #fitcouple #workhardplayhard #healthy #happy #healthyliving #namaste #aloyoga

Hi Laworkoutjunkie friends! China was amazing. We hiked The Great Wall and had amazing sight seeing jogs in Xi'an, Beijing and Shanghai. We couldn't have asked for a better trip but so excited to be heading back to LA to my kiddos and my normal regime. My daily harassing posts about working out will resume tomorrow!

Teddi is an accomplished equestrian and has been married to her husband, Edwin Arroyave, for six years. The couple shares two children, daughter Slate and son Cruz.

“We've got children the same age, so we connected on that level,” Dorit Kemsley spills. “She's got great banter, she's funny, she's sweet, she's down to earth. Her husband's really lovely.”

While not everyone looks to get along with the newbie -- Erika and Dorit are seen getting into it with her in the season trailer -- the whole cast seemed to have a similar read on their new pal: she doesn’t mess around.

“Teddi's down to earth, she cuts to the chase, there's no bulls**t and she does call some people out,” Lisa Vanderpump teases. “She's got a different flavor, and I think she's a great addition. Not everybody might agree with me, but for Kyle [Richards] and I, we adored her. So, she gets our approval.”

Teddi describes herself as an honest, casual tomboy who likes to have fun and laugh with her friends -- but she’ll never “sugarcoat” anything and hates when people beat around the bush.

“I really enjoyed getting to know her,” Camille Grammer adds. “You know, she's just real. She's salt of the earth … She's an accountability couch, so we have to, you know, the audience has to watch to see if she keeps any of the women accountable for their actions.” In case you’re wondering what exactly an “accountability coach” is, here’s Teddi’s description of the job.

“I help women accomplish their goals through fitness and wellness,” she explains. “I'm in constant communication with them. I help them achieve the goals when they're feeling a little stuck. I, myself, was in that same situation. I've been a weight fluctuator my whole life.”

“I'm not one of those women, like, ‘Oh, I had children and it just fell off! I don't know... I was running after them and now I'm so thin!’” Teddi continues. “No, I worked very hard and I know what it takes, so I'm helping women, empowering them to say, this is what you can do. You don't need to have an expensive trainer. You don't need to pay this food delivery system. You just need to get out and move, and I'll hold you accountable to do it and I'll remind you of that conversation that we had 10 days ago, when you said you wanted to change.”

Teddi replaces departed star Eileen Davidson, who walked away from the series after season seven to focus on her acting career. She’s currently starring on both NBC’s Days of Our Lives and CBS’ The Young & The Restless.

“She was juggling so many shows, honestly, that I totally understood that it was too much,” Kyle says. “It is a lot. You know, I'm shooting the Housewives and producing [scripted series] at the same time, and I found myself really being stretched thin. It's a lot. So, you know, that's where Eileen is. We love Eileen, though. We love Eileen.”

“I'm sad about Eileen not being here,” Lisa Rinna laments. “I come in by myself. I'm alone. I have no one. And you know what? I have to put my big girl pants on and flippin' deal with it.”

See how Lisa deals with it -- and get to know Teddi for yourself -- on The Real Housewives of Beverly Hills, airing every Tuesday at 9 p.m. ET on Bravo. For more on the new season, check out the links and video below.
