Britney Spears and Jason Trawick were out in LA yesterday for one of her son Sean Preston's Little League games. The proud mom also had her sister, Jamie Lynn, and little niece, Maddie, by her side. The whole Spears-Federline clan was in attendance — Sean's dad, Kevin, was there along with his pregnant girlfriend Victoria Prince. Britney and Kevin were together on Sunday too for another of Sean's matches, and afterward she treated Sean and his little brother, Jayden, to some of her homemade sweet tea. Sean's season may wrap up before Britney has to leave LA, as she'll kick off her Femme Fatale tour next month with opening act Nicki Minaj. Britney has taken some time away from prepping for her travels, though, to dedicate herself to helping with ongoing efforts to rebuild New Orleans in conjunction with the St. Bernard Project organization.
