Britney Spears looked superhot as she kicked off the 11th leg of her Piece of Me residency in Las Vegas on Sunday night. The show conveniently landed on the two-year anniversary of Britney's concert series at Caesar's Palace, and the singer seemed happier than ever to be returning to the stage for the first time since November. She flaunted her fit physique in a series of new costumes, including a sheer latex catsuit and black Playboy-bunny inspired onesie, and kept the crowd rapt with her dance moves and infectious smile. Britney, who is currently single, was also spotted wearing a not-so-subtle diamond ring on her left hand.
Before the big show, Britney tweeted a series of adorable photos while backstage with her sons, Sean and Jayden, writing, "Back in Vegas peeps!" She's been spending lots of sweet quality time with the boys during her break from the show, including attending their sweet holiday recital.
