The pop star graces the cover of People magazine this week with her adorable sons, Sean Preston, 9, and Jayden James, 8, where she's giving fans an inside look into her family life.
While these kids look similar to each other and to their famous mama, Brit says they have very different personalities.
"Preston is very opinionated, very expressive, and if he doesn't like something, he's going to tell you, But he has a huge heart, he's a good kid and he has manners," she tells the mag. "Jayden is sweet, very soft-spoken, kinda funny. He's adorable -- a momma's boy."
Just because the boys have a superstar mom, doesn't mean they're spoiled. The 33-year-old admits that homework and chores around the house are major priorities for them, and she's hesitant to give them an allowance.
"Preston just asked for a high allowance –- like $10 a week or $20 a week –- but we'll see!" she declares.
Spears, who co-parents with ex-husband Kevin Federline, also has a new beau in her life ... producer Charlie Ebersol.
"They relate to him really well and they have fun together," she says, referring to her boyfriend's relationship with her sons.
"I'm the happiest I've ever been," she gushes.
