Kristen Wiig Talks Leaving 'SNL' In Marie Claire

"Saturday Night Live" alumna Kristen Wiig graces the cover of the August issue of Marie Claire. Inside, she talks about her emotional send-off from the show, how she knew it was time to go and just how crazy the season finale after-party was.

In the issue hitting stands on July 17, Wiig explains how she didn't leave "SNL" just to make more movies like "Bridesmaids" -- she always knew she wanted to stay on the show for seven years, which she did.

“I know a lot of people probably assume, ‘Oh, she’s leaving because she is going to be doing movies now and things like that,’ which I will be. But I just always knew it was going to be seven and that was it," Wiig said. "I think maybe if I were 22, I could see myself staying a little bit, but it just felt like the right time.”

Her last episode of "SNL" ended with one of the most touching goodbyes to a cast member in the show's history, including a heartfelt waltz with Mick Jagger. Wiig, who was visibly moved by the gesture, explains how "surreal" her last moments as a cast member really were:

"You have all this stuff going on in your head, like, 'I can't believe seven years has gone by, and I'm going to miss all these people.' And I'm like, 'Oh, by the way, Mick Jagger is to my right, and I just danced a waltz with him.' So there's that," she said. "It was very emotional. I just wanted to get through it without breaking down in every sketch. Because nothing says comedy like breaking down.”

News of the finale's after-party featuring a performance by The Foo Fighters circulated the web, but Wiig reveals to Marie Claire just how crazy of a night the cast really had: when she woke up the next morning, she realized she had chipped a tooth!
