After touching down in a private jet, Brit headed to the Mirage Hotel and Casino, where she and her entourage (including hairdresser Kim Vo) had a luxury villa with a private pool. But instead she chose to sun herself at the Bare Pool Lounge in the VIP area.
“She was in her bikini and looked awesome," an onlooker tells E! News. "She looked really thin and happy."
Britney also took in the hotel's Cirque du Soleil show, Love, on Saturday night with her bodyguard and her assistant Brett. But did she ever meet up with Adnan?
Although the paparazzo was seen walking through the lobby of the Mirage, the two weren't seen together...in public, at least.
"I don't think it was a coincidence that he was there," a Vegas source says. "What are the odds?"
