Jenna Fischer showed up on Jimmy Kimmel's talk show in a towel

Jenna Fischer had a major wardrobe malfunction during a visit to Jimmy Kimmel's talk show.

So instead of a dress, she wore a white towel.

"I waited a little too long to get dressed, and then my zipper broke. And I panicked," The Office star told Kimmel.

But Fischer said her outfit had some upsides.

"I've never been more comfortable. I am mentally a little freaking out that I'm on a talk show in a towel, but I'm physically very comfortable."

The talk show host replied: "I feel like I ran into you at the spa."
