Many celebrities would choose to ignore a cheating scandal in the midst of a high profile concert residency, but not Britney Spears. In the wake of her break up with lawyer David Lucado last week, the "Perfume" singer admitted he was unfaithful during her Piece Of Me concert last night (Aug. 31) in Las Vegas.

"Well, by now everyone knows my boyfriend cheated on me," Spears told the Planet Hollywood crowd, according to MTV. The 5000 Britney faithfuls responded the news with a raucous roar of "Boos" (presumably aimed at Lucado, not Spears).

But despite her broken heart, Spears was optimistic about her prospects in Vegas, looking for a "hot guy" in the crowd, before landing on celebrity blogger Perez Hilton.

"But the best part of breaking up is going on first dates. OMG, OMG, I need a hot guy. Where are the hot guys here tonight?" Spears said before pulling Hilton from the crowd and riding him around on stage as a part of her "Freakshow" performance.

The Vegas performance is the first time Spears directly admitted that Lucado was unfaithful, though she had proclaimed that she was enjoying the "single life" on her Twitter and posted an Instagram video late last week about having a "s---ty day."

Lucado's cheating reportedly came to surface after Spears' father (who has conservatorship over her) found video of him dancing and canoodling with another woman and showed it to Spears, who then broke up with Lucado.

The two had dated for a little over a year.
