The O.C. star Mischa Barton has demanded a pay rise.

The 19-year-old actress, who plays troubled teenager Marissa Cooper, apparently wants a six figure sum for each episode that she appears in.

"Mischa’s the star of the show, and she feels her salary should reflect that," a source told The Mirror.

One possible reason for Barton needing more cash could be her relationship with Cisco Adler.

"Mischa winds up paying for a lot of their dates," the insider added.
