BRITNEY SPEARS - BRITNEY SPEARS DELIGHTS CAMPERS

Pop princess BRITNEY SPEARS stunned American summer campers in Yarmouthport, Massachusetts, by appearing on their final day to congratulate the 150 kids on their efforts.

And the excited youngsters had good reason to thank the SLAVE 4 U star - she paid for their places on the camp with her own money.

According to the NEW YORK POST newspaper, Britney also signed a pink guitar for an auction to be staged by the Los Angeles-based after-school programme, The Blues Lab, which supplied instructors to the camp.

Britney's brother BRIAN helps organise and run the camp.
