Britney Spears could be saying goodbye to Las Vegas. While attending the 2015 Teen Choice Awards on Sunday, the 33-year-old "Perfume" singer revealed to E! News that she's still unsure if she will continue with her Las Vegas residency show, "Britney: Piece of Me," after her current contract ends later this year.

"I'm not really sure. I haven't made up my mind," Spears said. "I really love doing the show. It's a lot, a lot of fun, but I'm kind of torn right now. I don't really know what I want to do."

Spears' show at Planet Hollywood kicked off in December 2013 and has so far been a huge success. The pop singer celebrated her 100th show on Friday. In 2013, TMZ reported that Spears was set to make at least $30 million during her two-year contract.

Last month, E! News reported that Spears had been offered a new contract which she left unsigned. If she decided to leave her Vegas show, her final performances would be from now until November, with final shows scheduled over New Year's weekend. 

Spears recently announced that she was in the studio working on new music, telling Billboard Magazine, "I'm gonna do [a new album] slowly but surely."

"There's a lot going on with my kids and schools and, you know, adding new sports and stuff like that. I'm gonna try to do my best to do an amazing album, but it's not my full priority right now," she said about balancing her career and personal life.
