Apparently the Good Charlotte star is fed up with his girlfriend's flirty ways - and that was before the heiress was spied cosying up to MySpace boss Chris DeWolfe recently.
"Chris is crazy about Paris," says a source. "He finds her very attractive - they've spent some time together, and he hopes Paris feels the same way."
Benji reportedly threatened to move out of their Hollywood Hills home over the issue but decided to give their romance another shot after a heart-to-heart.
A source close to the guitarist tells the Daily Star, "He was really fed up about this, but his attitude is, good riddance to her if she has really cheated on him."
