Griffin will play London's Palace Theatre, Shaftesbury Avenue June 19.
The one-night-only engagement marks Griffin's first U.K. appearance since 2007.
In a recent interview with Playbill.com, Griffin said that she is a fan of the theatre. "I don't go to as much as I would like to because I'm on the road all the time, but of course. I mean, look, I'm a gay man on the inside. Of course, I like theatre. I wanted to be Gypsy Rose Lee when I was six. Does that paint a fair picture? [Laughs]. I'm not saying my view of theatre is on target. It's a little skewed, but I love all the classics and, of course, I love the great female characters, and that experience of being at a great production, there's nothing like it. As you know, being at bad ones blows, and being at the good ones is sort of life-changing and great."
