Britney Spears Doubles Down On Her Vegas Residency

You have until 2017 to see her, so get on it!

Britney Spears is letting it ride. After kicking off her Britney: Piece of Me residency in Las Vegas last year, the singer has decided to keep the show right where it is at Planet Hollywood for at least another two years.

Spears, who reportedly pulled down $30 million over the initial 24-month run, confirmed the news during a weekend appearance on "Good Morning Britain" over the weekend. "The last time we chatted here on 'Good Morning Britain' to you, you just started that tenure," host Richard Arnold said. "It’s been extended for another two years."

"Yes, yes ... yeah, I’m very excited,” Spears said, confirming that she'll be working the stage in Vegas through 2017. Asked how she keeps up her stamina for the three weekly gigs, Spears said she has plenty of time to go back home and rejuvenate. "It's a nice balance," she said.

As for how she keeps her energy up when not chasing around her two skateboard-loving sons, Brit explained, "I love swimming. I swim all the time. I love going to the spas. I love cooking. I love studying with my boys and doing just normal things and stuff like that."

Looking back now at her days of traditional touring, Spears said she wonders how she ever managed it the old-fashioned way. "How did I even do it? Going to a different city every day," she said. "Being based in Vegas and having one show that you just keep going back to and the consistency of that is really grounding and really cool."

Also, Britney said she's in the studio and working hard on new music and ... she would love to collaborate with Katy Perry on a song!
