Britney Spears threw a family-filled birthday party for Sean Preston and Jayden James in LA on Saturday. The boys, who are turning two and three, were treated to a car and truck themed bash and given new mini cars with personalized vanity plates to ride around the party with their friends. Speaking of the attendees — Jamie Lynn and baby Maddie flew out, as did Lynne, while Jamie Spears was of course around. The birthday boys also hosted some celebrity friends like Evan McCarthy with mom Jenny and Kingston Rossdale without his parents. JJ and SP weren't the only ones getting gifts from Britney this weekend — she donated a painting of herself to a foundation that helps provide health services for low income women. With family around and good deeds on the mind, it looks like a very happy afternoon for the Spears family and these two precious boys.
