London: She is a single mother and pop star Britney Spears says she tries to wrap up her professional work while her two sons are away at school.
The singer, who has sons five-year-old Preston and four-year-old Jayden James, tries to balance career with family by timing her work around her children`s school schedule, reported Contactmusic.
"I`m usually pretty busy when I`m not working. I have two children, so I usually get them up in the morning, and I`m usually at the gym, and I help cook dinner sometimes ... a lot of the stuff that I do I do early in the morning when my boys are at school," said the 29-year-old singer.
The `Hold It Against Me` hitmaker who has made a powerful comeback with her latest hit album `Femme Fatale` also spoke of her nervousness to return to live performances.
"I haven`t been out on stage for a year. I have jitterbugs," added Spears.
The popstar described the shoot for the video `Till the World Ends` as grimy and says she worked hard for it.
"It would cost about USD 1,000 of studio time. It was a little much. It was grimy and sweaty but it was just sweat. You work through it," said Spears.
