Kat Graham is single. Multiple sources exclusively say that the Vampire Diaries star and her fiancé of about two years Cottrell Guidry have split. The two announced their engagement in October 2012. About a year later, Graham told E! News that their wedding planning was coming along beautifully. In January, at a Grammys after-party, Graham revealed that the nuptials would be taking place “pretty soon.” Graham added, “Next time you see me, I might be a married woman. Any day now.” Sources add that the couple may have called it quits last night when Graham got unusually tightlipped when asked about an update on the wedding when she arrived at the Diamond Ball with pal Nikki Reed.
