The cast of The Vampire Diaries certainly has its fair share of co-star romances. From Ian Somerhalder and Nina Dobrev, to Paul Wesley and Torrey DeVitto, to the former love of Candice Accola and Zach Roerig (RIP), there’s about as much sexual tension off the set as there is onscreen.

But not all of the cast chooses to mix business with pleasure. Case in point: Kat Graham (Bonnie), who’s been in a relationship with model/actor Cottrell Guidry since 2010.

In fact, after two years of dating, Kat and Cottrell have made it official, reportedly getting engaged on the weekend of October 27!

While there’s been no confirmation from Kat herself, that sparkling rock on her ring finger says it all! (Shall we start calling them Katrell for short?)
