And off-screen, she is two years in love with actor Josh Brolin (seen in this month's Hollow Man with Kevin Bacon and best known for hilariously licking Patricia Arquette's armpit in 1996's Flirting with Disaster)

Now Driver says she's happier than ever--in no small part because of Brolin (James Brolin's son and Barbra Streisand's stepson). "We've never been apart for more than three weeks," she admits. "We wrote each other the most beautiful love letters while I was on location for Return to Me." But don't jump to conclusions. "There was a rumor that we were engaged," Driver blurts with annoyance. "We're really, really happy, but not engaged." Still she's eager to start a family. "I can't wait!" she exclaims. "I'll be a really creative parent." And Driver clearly admires Brolin's parenting skills (he has two children from a previous marriage); "Josh is an amazing parent."
