Good Charlotte star Benji Madden is dating Australian actress and pop star SOPHIE MONK, according to media reports in the US. Celebrity gossip columnist PEREZ HILTON claims Madden is seeing the DATE MOVIE star, who parodied Paris Hilton's burger commercial in the film. Monk also appeared in the Adam Sandler movie CLICK and was previously linked to British stars Jason Statham and Jude Law. Madden, 27, was recently reported to be following in the footsteps of twin brother JOEL, by romancing an underage girl - Joel caused controversy by dating Hilary Duff when he was 24 and she was just 16. Benji was linked with 17-year-old CALEIGH PETERS, the daughter of movie producer CHRISTINE PETERS, after they were spotted dining together in Los Angeles last month (AUG06).
