When Canadian singer Celine Dion signed a contract with Caesar's Palace for a residency in Sin City, the game changed for the most famous town in Nevada, and among the newer residents for shows is Britney Spears' Las Vegas act in Planet Hollywood, which has earned her big money in the past few months - but it may be coming to an end.

At 33 years of age, Britney has done it all, as one of the richest and most successful pop artists of all time, remaining on top for over 15 years and a lifetime in the music business before reaching that Britney Spears Las Vegas residency, which may or may not last for a very short while now.

Speaking to E! Online exclusively about Britney Spears' Las Vegas residency, as she looked radiant during the past Teen Choice Awards 2015 last weekend.

"I'm not really sure," said the Princess of Pop, speaking about whether she'd keep that Britney Spears Las Vegas residency. "I haven't made up my mind. 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."

Britney Spears' Las Vegas show, "Piece of Me," began more than a year and a half ago at the AXIS auditorium in the Planet Hollywood resort in the city, and since December 27, 2013, the "... Baby One More Time" songstress has brought in revenue of more than $52 million for the famous casino, and The Huffington Post reports that she was making about $30 million for her 2-year contract.

According to International Business Times, her run has been a critical smash as well, earning her some top accolades last April as the best of Las Vegas as well as the best bachelorette party awards.

There's still no confirmation on whether Britney Spears' Las Vegas residency will continue.
