What would Donald Trump think? Miss Universe judge and “Rock of Ages” star Diego Boneta was spotted getting very close to one of the contestants on Wednesday after the show, a source exclusively tells Pages Six. We’re told the actor and Miss Germany, Alicia Endemann, were seen getting cozy at The Act at The Palazzo in Las Vegas after the contest at Planet Hollywood, staying out until closing time. “Diego and Miss Germany were having a heavy make-out session,” insisted a witness, who added the flirtatious behavior of the judge and the contestant raised eyebrows at the club and would certainly upset pageant organizers. But according to another insider, the pair didn’t kiss and were merely out dancing, along with Miss Belgium, Laura Beyne. But even if Boneta, a Mexican singer and actor who starred as Drew Boley in Adam Shankman’s big-screen production of “Rock of Ages” did take a shine to beautiful brunette Miss Germany, she didn’t make the final five fore Miss USA Olivia Culpo was crowned the winner. According to Endemann’s Miss Universe bio, the Hamburg-born beauty “loves to dance, sing, and play piano.” Reps for Diego, Miss Universe and Trump didn’t get back to us.
