Spears 's long, blond hair extensions pulled back in a ponytail, and she wears a white-and-turquoise cover-up over a bikini that reveals her chubby and cellulite filled backside.

Spears recently posted a message on her Web site saying she had been acting like a "bad kid running around with ADD (attention deficit disorder)."

"Recently, I was sent to a very humbling place called rehab. I truly hit rock bottom. Till this day I don't think that it was alcohol or depression," she wrote.

Meanwhile, UK gossips report that Spears saved an elderly couple from a jellyfish-infested beach
during her Mexico holiday.
The 25-year-old singer warned two older guests to be careful when strolling along the
picturesque waterfront.

She reportedly told the older couple: "Be careful, there are lots of Man o'
War jellyfish washing up on shore, you don't want to get stung."

In other news, Britney seems happy.

A source says: "She seemed happy and carefree with her friend."
