PARIS HILTON has confessed she broke up rocker BENJI MADDEN's romance with SOPHIE MONK - she was dating the GOOD CHARLOTTE star before he split from the Aussie model.

Benji has always maintained his engagement with Monk was over before he started dating the socialite, but Paris has revealed that's not altogether true.

In a new interview with Sydney's Sunday Telegraph, the hotel heiress confesses she fell in love with Madden shortly after the birth of best pal NICOLE RICHIE's daughter Harlow in January.

Harlow's father is Benji's twin brother JOEL.

She says, "Ever since Harlow was born I was over playing with her and visiting Nicole and Joel - and we just fell in love right away... He said he always had a big crush on me and when I finally became single it was great that we got together - it was the best.''

Paris revealed that the couple had been together for "like eight months".

But Monk's publicist made the announcement about the Monk/Madden split on 12 February, suggesting the rocker and Paris were dating before the 13-month engagement ended.

Paris just giggled when a Telegraph reporter asked if she had been a part of the break-up, before adding of Monk, "I never met her and I don't know her, so I have no opinion.''
