WATCH: Kathy Griffin Remarries Gay Couple

LGBT ally and fave Kathy Griffin had a particularly gay episode of her Bravo show this week.

On Thursday's installment of Kathy, she officiated a renewal of vows for a gay couple from her audience, Tim and Reuben, who have been together 20 years. She ended the informal ceremony by saying, "You may now tongue-kiss each other."

The show also featured guests Kristin Chenoweth, Josh Groban, and Eva Longoria, with the latter discussing her crush on Barbra Streisand. Watch clips below.
