One Tree Hill's Chase might've been introduced as a celibate "clean teen" in Season 4, but these days he's finding himself in a love triangle. "I like to blame it on the girls," Stephen Colletti jokes to "They came after him."

While his character has been getting close again with Alex, played by Jana Kramer, Colletti hopes he gets back together with ex-girlfriend Mia, played by musician Kate Voegele.

"[Alex is] more fun, but seems to be more racy so I don't know if that's good for Chase.  Mia is more the sweet girl who I personally think Chase would be better off with," he says.

In the interview below, the 25-year-old talks about how he was able to break out from MTV's Laguna Beach to become a working actor and why he and Lauren Conrad have met with a measure of success after their reality show.

The One Tree Hill finale airs Tuesday at 8/7c on the CW.
