Britney Spears Hits the Gym in LA | Pictures

Britney Spears hit the gym before stopping by Gelson's supermarket in LA yesterday. She was decked out in her workout clothes and accessorized with a necklace that read "Preston," her oldest son's name. Brit made the grocery run while her lawyers handled some unpleasant business — Britney's former manager is suing her and her parents over 2007 deals gone wrong. Despite the legal troubles, Brit's looking to the future. Britney just purchased an $8.5 million mansion in Thousand Oaks, CA. The X-Factor is also making moves, since this week she and the other judges selected which four contestants will appear on the next round of live shows.
