Benji Madden wants to marry girlfriend Paris Hilton insisting their relationship is genuine - and the socialite is "wife material". The Good Charlotte rocker is desperate to prove critics of their relationship wrong, and claims he fell in love with Hilton long before they even got together earlier this year.

He tells an interviewer on Sirius radio, "We were in love before anyone even knew we were together. We have known each other for a long time, and I've always known the real Paris. I always knew that she was like...wife material or serious girlfriend material."

Madden gushes, "You just want to get on top of a mountain and go, I'm in love! But your fans would probably make fun of you." And when asked if they could marry soon, he replies, "Nothing would make me happier. Wow, all right. Ok. I'm not gonna bet against you on that. We'll see. I'm very, very happy right now."

Babies could be on the horizon too; Madden admits babysitting his niece Harlow - whose parents are Nicole Richie and Joel Madden - has made him broody.

He adds, "Oh yeah, I babysit all the time. I love babysitting and I'm learning everything. I can change diapers now...One of Harlow's favorite songs is one of the songs on our record, so when I rock her to sleep, I'll sing it to her."
