'Work Bitch' superstar Britney Spears has opened up about juggling an international pop career with being a mother and confessed that she has to make it work because her family are her passion. 

Speaking to the Associated Press about her fame and family life, Spears explained that Sean, 8, and 7-year-old Jayden, come first so she has to step into the mother shoes as soon as she gets home from work:

"Once you've done a shoot... you have to come in and do homework and fix dinner twice and it's a lot of work. But I think as women we just manage it, we make it work."

She also joked that she had to keep an eye on what she ate before shooting her latest music video, but added that it was hard to stick to because she enjoys late-night snacks: "I love to eat my popcorn at night!"

When asked what she ate after the 'Work Bitch' video was finished, she confessed: "Just chocolate, chocolate, chocolate."

Speaking about 'Work Bitch', she admitted that it's a relatable song: "I think it will make girls not feel alone in this situation. When they're alone in their room and they broke up with their boyfriend, they have a song they can go to and listen to, just makes them feel better about themselves."
