Former The Vampire Diaries costars Arielle Kebbel and Zach Roerig have called it quits. "I haven't been in a relationship in quite some time," Kebbel, 41, revealed on the Thursday, February 19, episode on the "Off the Vine" podcast before host Kaitlyn Bristowe jokingly offered her congratulations for the actress' single status. The actress continued, "I feel like that's a very vulnerable and important conversation you just brought up because I've had this conversation with my girlfriends going through either a breakup or a divorce.
