[article id="1635857"]Justin Bieber and Tina Fey[/article] aren't necessarily the likeliest candidates to share screen time, but that's exactly what happened over the weekend, as the "Baby" singer was the special musical guest on the latest episode of "Saturday Night Live," hosted by the "30 Rock" star/writer.

In an exclusive interview with MTV News on Sunday morning (April 11) after the show, Bieber said he was thrilled to participate in "SNL," particularly alongside Fey. "It was fun, just acting [with Fey]," Bieber said. "It was cool to get to be a part of 'SNL.' "

Musical guests on "Saturday Night Live" are traditionally relegated to two concert appearances over the course of the show, but Bieber happily joined in on several of the evening's skits. In one particularly memorable segment, Bieber played a mediocre science student named Jason Deeps, but what he lacked in academic knowhow he more than made up for with his "dreamy Christmas elf" looks, causing his teacher (Fey) to fantasize about a romantic life between the two of them involving panini sandwiches and "some Spanx to make her teeny."

"It was hilarious and it was a lot of fun to do," Bieber laughed while recalling the skit. "I just tried to act and I thought of bad, bad thoughts [to distract myself]."

When asked if he had an easy time flirting with Fey in the skit, Bieber smiled and answered: "Yeah!"

"She's cool," he said of Fey, whose romantic comedy "Date Night" alongside Steve Carell premiered this weekend to strong box-office numbers. "She's a really nice person. She's really down to earth, not really like Hollywood. She's cool. And she's cute too!"

Bieber said the chance to appear on "SNL" alongside Fey and the rest of the cast was a thrilling opportunity. "It was a lot of fun," he said. "I really had a great time doing it. Like I said, it was 'SNL'!"
