I had a quick chat last night with Rachel Bilson, formerly of The O.C. but soon to be seen in a sci-fi adventure film, Jumper with Hayden Christensen, whom she may or may not be dating (you can see them both in the movie's trailer below). It was evening in the east but late afternoon in L.A. and Rachel, 26, was driving to pick up her sister - a kindergartner - at school. "My dad remarried and they have two little ones," she explained (her second sibling is 1). She adores them, no surprise, and says she knows she'd really like to have children one day but she's not ready yet. She has no desire to be part of Hollywood's latest trend - having a baby.  Bilson got to travel to make the movie and among the places it was shot was Rome. She describe shooting scenes in the Coliseum as the sun came up before the tourists arrive as one of those moments where you recognize that life doesn't get much better.
