Stars are coming out of the woodwork to be a part of David Letterman’s “Goodbye Tour.” Some say so long, others make jokes but Tina Fey may have just trumped them all.

The former Saturday Night Live and 30 Rock star was a guest on the Letterman's show Thursday wearing a stunning blue dress. It was her 20th appearance on the show.

"This is it, I'm never going to wear a fancy dress on a talk show again," Fey said to the Late Show legend. "What, am I going to put a dress on for Jimmy? That's creepy, he's like my brother."

Fey said, "it's very hard work," dressing for a talk show. "I don't know if you're aware of the contraptions there is under here."

Fey goes on to tell Dave, “my gift to you is, I want to give you the dress."

With that, Fey asks Letterman to unzip her and she wiggles out of the dress revealing a body suit with "goodbye Dave" on the front and "#last dress ever" on the back. A blushing Letterman laughs as Fey kicks the dress toward the camera.
