Britney Spears says her dream vacation is a skiing trip.

The 29-year-old singer admits her skills on the slopes are limited but she enjoys the sport and would love to go on a snowy break with her boyfriend Jason Trawick and her sons Sean Preston, six, and five-year-old Jayden James.

She told Stylist magazine: "My dream holiday would be with my children, of course, and my boyfriend. We'd probably just go skiing somewhere really beautiful and have Hot Chocolate, in a cabin.

"I'm not a good skier but I enjoy the process of learning. I do get frustrated when I see little kids go really fast beside me but, for the most part, once you get going and you've got an idea of how you're going to ski, it's kind of fun."

The 'Gimme More' hitmaker admits it is hard to go to public places because of her fame, and she sometimes contemplates going out in disguise so she isn't recognised.

She said: "In some situations I'd love to be able to put a disguise on and go to a restaurant and not be noticed."

As well as skiing, Britney has another dare-devil ambition.

She said: "I would like to go skydiving."

Although she is keen to go an activity holiday, Britney she struggles to stay motivated to go the gym, even though she always feels good after working out.

She said: "[My biggest daily challenge] is trying to get up and go work out in the morning. I haven't worked out in, like, two weeks.

"Sometimes it's hard to be motivated. But once you've got up and do it you feel like you've conquered the world."
