( Fafarazzi ) - After a long weekend of frolicking on the Costa Rican beach in her bikinis, Britney Spears hopped on the private jet back to LA yesterday evening. She was showing off her extra tanned body with her agent Jason Trawick right behind, but still no sign of her host for the weekend, Mel Gibson. A moment of R and R seems like just what she needed before getting back to her LA life, and I'm sure her boys will love any souvenirs she picked up on her mini vacation. She's supposedly back in town to work on an even more involved custody deal, so hopefully this trip helped clear her head for the important meetings.
