Britney Spears

British music producer Mark Ronson has joined the ranks of celebrities showing support for troubled pop singer Britney Spears, and believes she has the willpower to bounce back from her recent problems.

Ronson - who has remixed the starlet's hit single Toxic for his latest album Version - is confident Spears will benefit from her recent battle with substance abuse, because they expose her as a real person, with real problems.

He says, "She can definitely come back. She's shown she's a bit loopy and as messed up as the rest of us."
