'Selling Sunset' star Amanza Smith is 'definitely' not dating Zac Efron

A representative for "Selling Sunset" star Amanza Smith shot down internet rumors that the reality TV realtor is dating "High School Musical" star Zac Efron.

“They are definitely not dating," Smith's rep told TODAY on Wednesday.

Speculation about the pair started earlier this week after Smith recently celebrated her 45th birthday in Las Vegas with friends.

In a photo shared by HGTV star Tarek El Moussa (who is married to "Selling Sunset" star Heather Rae Young), the 34-year-old Efron and Smith posed side-by-side with the "Flip or Flop" star and Young in a group photo taken at a UFC event. Apparently, that's all the internet needed to begin "shipping" the two, as they say.

Earlier this month, Smith talked in-depth with TODAY about the latest season of the Netflix reality show and her on-and-off-screen struggles as a single mom.

She said that when she first got divorced from former NFL player Ralph Brown, with whom she shares daughter Noah and son Braker, now 12 and 10, she had to take whatever jobs she could to make ends meet.

“When I got my divorce, I cleaned houses, I worked at BCBG retail, I was walking dogs. I did every odd job I could to make money to support my kids because I wasn’t getting child support,” she explained. “So that misconception really bothered me. Still to this day, people who don’t know my story know I have two kids and their dad was an NFL player. But they probably just don’t know how hard I worked. They don’t know what we’ve been through.”

Things seem to be working out for Smith so far though, as she's a successful realtor with the now-famous Oppenheim Group and "Selling Sunset" is slated to return for a fifth season.

When she spoke with TODAY earlier this month, Smith added that she's happily dating someone but wouldn't reveal who.
