See How Britney Spears Celebrated Her Son's Birthdays

Pop princess Britney Spears is quite the mom, with residency at Planet Hollywood in Las Vegas as well as launching her own lingerie line, she also made time to celebrate her sons birthdays at a skateboard themed party on Friday.

Spears sheds a lot of light into her life via her instagram and Friday was no exception as she shared a photo of her sons Sean Preson, 9, and Jayden James,8, as they posed in matching plaid shirts and skate gear. They seemed to be enjoying their very boyish themed party.

The "Pieces of Me" singer captioned the photo, "Happy Birthday to my two little baby boys. They are growing up too fast!!!"

The two brothers have birthdays two days apart, Sean Preston's is on September 14 and Jayden James is on September 12, therefore a joint birthday party seemed absolutely appropriate and mama Britney knew how to make it happen!

The boys each got skateboards with their names painted on them.

In 2004, Spears became engaged to dancer Kevin Federline. The relationship was highly publicized and became even more so when she gave birth to her first child Sean Preston in 2005. During a tremulous year fighting child advocates for driving with son Sean on her lap during a paparazzi swarm she then announced her second pregnancy with Jayden, which had the media at high alert even further. Jayden was born in 2006. During the same year she filed for divorce to Kevin Federline in November 2006 citing irreconcilable differences.

Her son's are with her most of the time in Vegas and in the I Am Britney Jean special the singer revealed how her two-year residency would be good for keeping her family in one place. "I figured it's be a really good place for the children and the family. It was kind of like an ideal situation."
