Kevin McKidd on 'Grey's Anatomy''s New Love Triangle

When Owen Hunt (Kevin McKidd) scrubbed into Seattle Grace Hospital on "Grey's Anatomy" last season, he quickly found himself attracted to Cristina Yang (Sandra Oh), but acting on it was another matter. Having just returned from the war in Iraq, he was dealing with Post-Traumatic Stress Disorder -- and he tried to strangle her.

Now in therapy, Owen and Cristina are moving on with their relationship, or are they? Owen just invited Dr. Teddy Altman (Kim Raver) into the mix. He thought he was giving Cristina a present by bringing a top-notch heart surgeon to Seattle Grace, but Teddy has romantic feelings for Owen, so is she really going to be a gift for himself? A love triangle can't be too far behind!

Kevin talks to ET about the two women in Owen's life, McNicknames and all the babies on the set.
