The Grey's Anatomy actor revealed on his website in March that he and the chef got married and are expecting their first child together. "Arielle and I are so happy to announce our marriage and new baby, who is soon to join our growing family," Kevin wrote. "Close friends and family came together with my Grey's family to share in our celebration day – an intimate, low key gathering culminating in a Scottish Ceilidh dance." Kevin already shares two kids, Joseph and Iona, with ex-wife Jane.
