'Up All Night' Welcomes Stevie Nicks To Ava's Talk Show (VIDEO)

According to ABC News Radio, it was Stevie Nicks herself who made her guest appearance on "Up All Night" (Thu., 9:30 p.m. ET on NBC) this week happen. After Ava said she was going to try and get Nicks to appear on her talk show within the show way back in the pilot, Nicks decided to reach out to "Up All Night" and help make Ava's wish come true.

Even though Nicks has made several TV appearances within the past year, "Up All Night" marks the legendary singer's first foray into acting, according to New Jersey Newsroom. It wasn't much of a stretch, though, as Nicks did play herself, albeit a more mystical and mysterious version.

Fans who stuck around for the closing credits were treated to a fantasy duet between Christina Applegate's Reagan and Stevie Nicks.

Catch "Up All Night" every Thursday at 9:30 p.m. ET on NBC.
