Jersey Girl Liv Ingela Ratledge US Weekly March 29, 2004 LIV TYLER ROCKS - AND NOT JUST BECAUSE SHE'S THE DAUGHTER of Aerosmith frontman Steven Tyler, 56, and the wife of British singer Royston Langdon, 31 (she wed him last March).  As a free spirited grad student in the comedy Jersey Girl, out March 26, the 26-year-old New York City native shows off her own surprisingly good pipes - and makes out with her costar Ben Affleck, 31. In Jersey Girl, you and Ben get it on in the shower.  Do tell. We were actually in a tiny room using disgusting, pumped-out trailer water.  We had clothes on and our pants were filled with water.  But I've known Ben a long time, and you just try to have fun. Did your costar Raquel Castro, 9, give you the motherhood urge? I'm looking forward to having a family.  I'd definitely like to have kids in the next couple of years, but not tomorrow.  I'm enjoying being married. What does your dad think of your being so domesticated? At my age, he was making horrible decisions.  So he always says, "Where do you come from?"  I'm married and I have a home, and he's surprised that those are my priorities at such a young age. Do you ever catch heat in Hollywood for not being a waif? In the past couple of years, I was a bit heavier, and people were so critical.  It's ridiculous - I'm not a supermodel, I'm an actor.  I just try to be healthy and stay comfortable with myself.
