Mario Lopez’s fiancée crashes his bachelor party

History didn't get to repeat itself for Mario Lopez. His fiancée, Courtney Mazza, crashed his weekend-long bachelor party in Las Vegas — after all, he cheated on his first wife during his bachelor party in 2004.

On Saturday night, the "Extra" host got quite a surprise when the mother of his 2-year-old daughter Gia stepped onstage in lingerie to perform with the Pussycat Dolls dance troupe at the Planet Hollywood Resort. Clad in a bustier, fishnets, and "I [heart] Mario" red satin gloves, Mazza put on a sexy show for her husband to be and 15 of his friends.

Although the former Broadway dancer took a lot of heat on Twitter for crashing the boys' weekend, who can really blame her? Last year, Lopez admitted to the longstanding rumor that he had cheated on Ali Landry during a wild bachelor party in Cabo, after he lied to her and said he was going fishing with his cousins. "It was spring break ... everybody was hanging out," he told Howard Stern. "That was a situation where I was not mature and man enough."

But that one indiscretion wasn't the only time Lopez, now 38, cheated on the former Miss USA. Not long before they walked down the aisle, Landry says she had "a feeling in my gut" that he hadn't been faithful, but she went through with the wedding anyway because it was set in Mexico — where Lopez will also marry Mazza later this year — and her family already had made their travel plans. But just days after saying "I do," she said she tapped his phone to get her proof. "And right after the honeymoon I started getting phone calls from these girls," Landry told Wendy Williams this past March. "I confronted him and he still to this day, he denied it and never apologized." The marriage was annulled two weeks later.

Let's hope Mazza has better luck!
