Britney Spears is extending her Las Vegas residency for two more years.

The 33-year-old singer was due to complete her 'Britney: Piece of Me' series of concerts at Planet Hollywood at the end of this year but revealed that she has signed a new deal to continue.

She announced the news during her concert on Wednesday (09.09.15) and told E! News: ''I'm not ready to leave Vegas yet! And I just really really love this show and this city. I'm so proud of the show, and my band, my dancers and my crew have all become such a family to me. When it came down to me really having to make this decision, I just couldn't imagine ending my residency at the end of this year.''

While she is extending the show's run, Britney revealed that fans can expect some changes to her shows.

She explained: ''I definitely have some major changes planned. I'm getting together with my team this week to go over the set list, design some new costumes and dream up new props.

''There are a few songs that that I really want to add to the show. It's very exciting! If you haven't seen the current show yet, you should come out before the end of the year.''
