Britney Spears' former lovers spent a weekend in Las Vegas - but while they didn't spend time together, they did attend the same event.
The "musician" who married Spears, Kevin Federline, took to a Justin Timberlake concert while in Sin City, possibly to enjoy the tune "Cry Me A River" which was reportedly penned about his then-girlfriend's infidelity.
While the newly single "Sexy Back" singer was in town to perform at the MGM Grand casino, K-Fed was there to catch the World Extreme Cagefighting event at the Hard Rock Hotel.
The former Spears men both partied at hot spot Tao, but while they didn't meet, reports reveal that Federline sat next to some of Timberlake's friends in the club's VIP section.
While Fedex was once famous for his partying and gambling while in Vegas, during his marriage to the "Toxic" singer, fellow club goers say he is now singing a different tune.
One witness said, "He wasn't drinking much and really only talked to a couple of his friends. It seems like he's trying to move on from past Vegas visits where it was all about the bling bling."
Spears was in Vegas just days before the boys, introducing her new boyfriend Isaac Cohen to what his future may hold.
