Britney Spears addresses break-up on stage

Britney Spears acknowledged her now-ex-boyfriend David Lucado's infidelity by slyly joking about the break-up during her Las Vegas concert on Sunday (31Aug14).

The Toxic hitmaker revealed she is single again last week (28Aug14), amid rumors suggesting her former beau had been caught on camera dancing and locking lips with a new lady.

And, during her Piece Of Me residency show at Planet Hollywood, Spears appeared to be ready to move on from Lucado as she openly addressed the scandal.

She told the crowd, "Well, by now everyone knows my boyfriend cheated on me. But the best part of breaking up is going on first dates.

"Oh my God, oh my God, I need a hot guy. Where are the hot guys here tonight?"

Spears scanned the audience for a volunteer to come up on stage and she surprised fans by choosing celebrity blogger Perez Hilton from the crowd.

While singing her track Freakshow, a leash was tied around his neck and Spears led him around on all fours like a dog - a stunt she has previously performed with celebrity guests including Lance Bass and Nicole Richie.

Spears began dating Lucado early last year (13), following the breakdown of her engagement to agent Jason Trawick.
