Britney Spears In Jellyfish Rescue

Britney Spears saved an elderly couple from a jellyfish-infested beach during her Mexico holiday.

The 25-year-old singer - who stayed at Punta Mita's Four Season hotel over the weekend - 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."

Britney - who travelled to Mexico with a friend on Thursday (31.05.07) and arrived back in Los Angeles on Sunday (03.06.07) - showed off her tanned and toned figure in a skimpy thong bikini during her relaxing sunshine break.

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