Britney Spears' eldest son will perform with her in Las Vegas.

The pop princess confirmed she has inked a deal for a two-year residency, called 'Piece of Me', at the Planet Hollywood Hotel and Casino in the US gambling capital, during her appearance on 'Good Morning America' today (17.09.13), where she shared juicy details about her rumoured $310,000-a-night performances.

Asked whether her sons Sean Preston, seven, and Jayden, six - her children with ex-husband Kevin Federline - would appear on stage when she performs her 'Smurfs 2' soundtrack single, 'Ooh La La', Britney revealed: ''Preston will probably be on stage but I think Jayden would have a hard time with it.''

The singer is excited to be taking up a residency in Las Vegas and insisted she won't be resting on her laurels for the concerts, which kick off on December 27.

Former 'X Factor' judge Britney said: ''I love Vegas. The energy is really good. I'm going to do my greatest hits, but I'm going to have to put some of my new material in to keep it fresh.''

The 31-year-old blonde star has been hitting the treadmill hard in preparation for the gigs and can't wait to take to the stage.

She said: ''I'm definitely ready. I sometimes have training for five hours a day.''

The sexy star also praised Miley Cyrus - who has cited Britney as her idol - and her controversial performance at the MTV Video Awards (VMAS) this summer, which saw her grinding up against Robin Thicke in nothing but nude-coloured latex underwear.

Britney mused: ''I think anytime you do a performance that's that memorable you'll get criticism. I think she's doing her thing and being herself so I give props to her.''
