Justin Chambers plays surgical intern Dr. Alex Karev, another character who's had quite a few ladies but continues to pine for Dr. Stevens.
In real life, Justin has been married for 12 years and has five kids, ages 5–12. "Having five kids, it's really nice to have a job, a successful show," he says.
Justin says he's amazed at how fans have embraced the show. "It's awesome, you know? I mean, when we shot the show we had no idea of an air date or how it would turn out," Justin says. "It's nice walking down the street and see[ing] people smile—and they really watch week to week and they really enjoy the show."
