Jenna Dewan is confident Jennifer Lopez and Alex Rodriguez will get engaged (Exclusive)

Jenna Dewan doesn't think Jennifer Lopez will have to wait long for Alex Rodriguez to put a ring on it. 

"I mean, I'm sure that's happening," the dancer-actress exclusively told ET's Leanne Aguilera during the NBC Upfronts in New York City on Monday. 

Dewan, 37, works with Lopez on World of Dance -- which premieres its second season on May 29 -- and has no shortage of nice things to say about the triple-threat star, gushing that she's "looked up to her my whole life," .

"I need her secret. I'm telling you, half the reason I did this show was to find out Jennifer's secrets and I have not done it yet," Dewan said of the 48-year-old entertainer. "I think it's just natural, which is the most annoying part of it all. She just like kills it. She can still own a stage. Ugh, she's everything!"

Lopez's fellow World of Dance judges, Ne-Yo and Derek Hough, also think Rodriguez is gearing up to pop the question.

"If you've ever seen the two of them together, it's pretty much the next step. They're, like, annoyingly cute," Ne-Yo, 38, shared. "Like, stop touching each other."

Hough, 32, only has one thing in mind when it comes to Lopez and Rodriguez's potential engagement. "I'd be like, 'Cool man, where's the party? Let's go'" he quipped.

In March, a source exclusively told ET that the power couple, who celebrated their one year anniversary earlier this year, have talked marriage.

"J.Lo and A.Rod are on the same page and want the same things," said the source. "They've discussed marriage and what their long-term plan is."

Another source added, "Their relationship keeps blooming. They just make each other better. They push each other to be better people, and that works for them."

"They complement each other well. They are both driven business people with the same background and are passionate about their charitable efforts," the source continued. "Their families are now blended and live together."

For her part, Lopez has been pretty open about being ready for Rodriguez to put a ring on it. While on set of the music video for her song, "El Anillo" -- which translates to "The Ring" -- she explained to ET the meaning behind the lyrics which seem to hint at an engagement. 

"It's more about the value of it. It's kind of like, 'If you want me in your life you have to give me the respect and place in your life that I deserve,'" she said. "And I think a ring sometimes is a symbol of that but it's more of a symbolic thing."

Lopez also appeared on The Tonight Showand further dished on what the song means to her.

"No pressure!” she said. “The song is definitely about that, it is, but I felt like it was kind of something that all women get to a point where they say, ‘OK, what’s up?’ [points to ring finger] Like, we’re good, everything’s great, what’s going on? Am I staying or am I [going]?’”

The next day, Rodriguez, 42, stopped by The Tonight Show and recounted reading the lyrics to the song for the first time.

“I’m reading the piece of paper like this and it’s the song,” the former New York Yankees player told host Jimmy Fallon of one night in the recording studio with Lopez. “I know nothing about music. I read the song and I go, ‘Babe, it sounds like they’re talking about us.’ And she goes, ‘Yeah! They made it for me.’ I heard it for the first time and I knew it was going to be a smash the first time I heard it.”

Though he was mum about any future proposal plans, Rodriguez assured the host, "When it happens, Jimmy, you’ll be the first to know!”
