Earlier this week, Efron was seen with "Selling Sunset" cast members Mary Fitzgerald, Amanza Smith, Tarek El Moussa and Heather Rae Young at a UFC event in Las Vegas. Thanks to an Instagram post from El Moussa, where Smith and Efron appeared to be a little close for comfort, dating rumors began spiraling.

Unfortunately for fans of "AmanZac" (that would obviously be their celebrity couple name), the two are not romantically involved. TMZ confirmed on December 14, 2021 that there is "nothing going on" between Smith and Efron. In fact, Smith is allegedly dating for a pro soccer player. Meanwhile, according to Us Weekly, Efron's upcoming "busy year of filming" won't allow time for a relationship.  

So how did the reality TV darling and hunky star cross paths in the first place? According to TMZ, Efron was coincidentally in the same restaurant as the "Selling Sunset" cast, and hopped in for a quick photo.

There you have it — mystery solved!
