Britney Spears says her children are 'in awe' of her live performances.

The singer has two sons ' six-year-old Sean Preston and Jayden James, five ' with ex-husband Kevin Federline.

Britney is in the middle of her Femme Fatale tour and has revealed her boys love to watch her concerts. They are showing a keen interest in dancing and Britney believes they will follow in her footsteps one day.

'They are in awe,' she told Daybreak when asked if her kids enjoy her concerts. 'They come home and try to copy all the dancers and their moves. They try to get on their heads and do spins, so I think they will definitely be in the entertainment business.

'They are with their father 50 per cent of the time so they go back and forth. They have been doing that for a while now. So when I am on the road they come with me and they love being on the road. When I was younger I was always on the road and doing stuff and it is just always exciting.'

Britney also addressed rumours about Britain's Duke and Duchess of Cambridge. It was reported the star was keen for Prince William and his wife Kate to watch her Femme Fatale show when she takes to the stage in the UK.

She has now revealed she would love to perform for the royal couple.

' don't know, I am sure they are very busy, but if they could squeeze it in it would be cool,' she said, before personally addressing the newlyweds. 'You guys are totally welcome to come to my show if you like.'
