Brit’s looking to be in great shape a she rocks a bikini while in the Caribbean. She has completed the North American leg of her tour and is taking a break. Spears is joined by her rumored boyfriend and agent Jason Trawick.

The couple splashed around in the pool and enjoyed the sandy beach.

But the couple aren’t alone. Britney’s dad and brother are with her, and yes, so are her sons.

Sean Preston and Jayden James are two happy little boys right now. Hanging with mom at the beach, getting sand in their diapers as they build sandcastles..

They even got to go see the dolphins.
