Britney Logs Studio Time in Miami Then Jets Back to Her Boys

Britney Spears and Jason Trawick touched down in Miami on Thursday, and he was by her side on both Friday and Saturday to work in a record studio. They hopped on a flight back to California yesterday morning, while Kevin Federline and his girlfriend Victoria Prince spent the day with Sean Preston and Jayden James at an LA park. Britney and Jason were back in time to attend last night's Grammys, where she turned a few heads with her revealing Dolce & Gabbana dress and bodysuit and simple makeup. She didn't end up taking home a statue for the year's Best Dance Recording, but Brit sounded excited to just take in the performances.
