You Won't Believe How Big Britney Spears' Children Are Now!

While Britney Spears has been through a lot in the lime light, her proudest achievements are definitely her sons Sean Preston, 9 and Jayden James, 8. 

Sharing her parenting duties with her ex-husband, Kevin Federline, "my kids come first in my life, bottom line" says Spears, chatting to PEOPLE magazine. 

The boys are already doing homework and Britney has enforced a rewards system, where the boys are able to get a new toy per month if they reach a certain number of A's. 

The boys also have their own personalities, with Sean being opinionated, expressive but very loving and Jayden being more sweet, soft-spoken and funny - a serious mummy's boy!

The celebrity kids even do chores, including taking out the trash, so they are earning a weekly allowance too. 

Britney's current boyfriend is producer Charlie Ebersol, whom the boys adore!
