Britney Spears scratches her ass on a beach in Costa Rica

Right.now,.Britney Spears is on holiday, spending a few days in Costa Rica. She was spotted yesterday again on the beach, this time with her agent Jason Trawick and another assistant.

She put her huge fat-ass on an ATV, and went for a ride with Jason. I don't get it.. She was supposed to spend the time with Mel Gibson, her papa, she was supposed to teach him all the 69 positions..

What had happened? Has she changed her mind? I bet this son of a bicch pretty lady, Jason Trawick, wants to take her in his bad, want to sign some papers and be the next Britney Spears' husband..

Anyway..There is something more I don't understand.. First, why does she look like peeing in the waves?

And second, does she have any problems with her ass, while she's scratching her butt in each photo..
