What happens in Vegas may not stay in Vegas.
After sparking marriage and pregnancy rumors at the Billboard Music Awards on Sunday, Machine Gun Kelly and Megan Fox also took revelers guessing Diddy’s after-party at Las Vegas’ Tao hotspot.
The pair arrived at the club in a hot pink stretch limo, and Fox “immediately hit the dance floor,” we’re told.
The actress, however, did not drink alcohol despite Diddy’s Deleon tequila and Ciroc vodka flowing freely for her VIP guests.
“She hasn’t had a drink all night,” a source told Page Six.
Last year, Fox, 36, said in an interview that she gave up alcohol in 2009 because she got “belligerent and said a bunch of shit I shouldn’t have said about the red carpet” at the Golden Globes.
Still, people at Diddy’s party speculated after the couple sparked rumors earlier in the evening when Machine Gun Kelly, 32, took the stage at the Billboard Music Awards. He performed his song “Twin Flame” and said, “I wrote this song for my wife.” He followed with, “This is for our unborn child” as a heartbeat sound played.
Representatives for the couple have not confirmed whether or not they are expecting – or whether they are married. They got engaged earlier this year.
The couple also celebrated Fox’s birthday at midnight when Tao staff presented them with a platter of desserts, complete with a large carousel horse shooting sparklers. His birthday is May 16.
Diddy was greeted with a huge presentation of his Deleon Tequila when he arrived at the club as his celebrity friends came out to celebrate. Cara Delevingne, Janelle Monáe, Jermaine Dupri, his son Justin Combs, Mary J. Blige, Nelly, Timbaland and Usher all showed up for the party. Diddy – who recently announced his return to music – got Heidi Klum dancing at his table, and he and Lil Kim jumped on the mic and rocked the crowd with DJ Chase B.
Brazilian singer Anitta and French Montana were also present after dinner, we learn.
