Tina Fey had a nip slip while wearing a sexy dress recently. The "Saturday Night Live" star exposed her cleavage for a second time in a new "SNL" promo after her now-infamous 2013 "Emmys" wardrobe malfunction. 

According to Hollywood Life, Fey was only poking fun at herself by exposing her cleavage for a second time during the funny clip.

The actress will host the premiere of the show's 39th season on Sept. 29, but not before making fans laugh about her embarassing dress malfunction. The funnywoman casually flashed her assets in a very hilarious way in the video with "SNL" cast member, Kenan Thompson. 

After Thompson announced that Fey would is back and hosting the premiere, he makes fun of the actress' nip slip.

"There will be no more wardrobe malfunctions like there were at the Emmys...," Thompson said in the clip. "I mean, unless you want to do one. I think it would be funny."

Fey crossed her arms and said, "No Kenan. It's not going to happen again."

As the actress unfolds her arms to say "It's under control," her blazer opens revealing her cleavage. And as Fey realizes she forgot her shirt, Thompson makes a hilarious face.

The "Mean Girls" star had the notorious nip slip onstage while accepting the award for "Best Comedy Writing" at the Emmys on Sunday. She wore a royal blue Narcisco Rodriguez dress that was ultra-sexy and low-cut, HL reported.
