Britney Spears celebrated the birthdays of her two sons, Sean Preston and Jayden James Federline, on Saturday. Sean Preston turns nine of Monday and younger brother Jayden James turned eight on Saturday–warranting the double birthday celebration.

The birthday bash took place at the Skatelab skate park in Simi Valley, California.

Britney Spears took to social media, sharing photos of the celebration on Instagram.

“Happy birthday to my boys…. love you so much Jayden and Preston!” the “Toxic” singer captioned this first shot, of her with her sons.

Britney later shared a special thanks to Skatelab that included a photo of the birthday cake she ordered for her boys.

“Thank you @skatelab and @lindacohencakepops for making this day so special,” she captioned the shot.

Kevin Federline–Britney Spears’ ex-husband and father of Jayden and Sean–remarked about the fabulous birthday cake, too.

“This cake is so dope.. Jayden and Preston Bday cake… #imadj,” he wrote as a caption of a close-up of the cake.

Britney Spears certainly threw an amazing birthday party for her sons. The day didn’t end with the party either. It seems Britney and her boys rocked out to some tunes in the car on their way home–to one of the summer’s hit songs, “Cheerleader” by OMI.

Do you suppose Britney Spears’ sons get double-duty birthday celebrations? Will Kevin Federline host a bash as well for their boys?
