Mischa Barton has apologised to her fellow O.C. cast-members over reports that she demanded a pay rise.

The actress, who plays Marissa Cooper on the US drama, is trying to make it up to her co-stars following rumours that she requested a six-figure sum for each episode she appears in.

"Mischa is really embarrassed because the claims have been wildly exaggerated," a friend told the Daily Star. "So she's been making amends by home baking and hand delivering."
