Britney Spears has proved she's back in shape again by donning a yellow string bikini on the beach in Hawaii.

The gorgeous singer was joined on the break at the luxury resort by her boyfriend Jason Trawick and looked better than we've seen her for a while.

Britney has recently finished filming her guest appearance on hit US TV show Glee and we hope things are on the up for her again.
