Selena Gomez stopped by “Late Night with Jimmy Fallon” Tuesday night (March 19) to promote “Spring Breakers,” her new grown-up romp co-starring Vanessa Hudgens and Ashley Benson. Gomez describes it as, “They go on spring break and do a lot of bad things.”

But in addition to the interview, Gomez lent her golden pipes to a duet with Fallon on “Mario Kart Love Song,” which was kind of awesome.

Lyrics include: “You be my Princess and I’ll be your Toad. Follow behind you on Rainbow Road … You be my Toad and I’ll be your Peach. Follow behind you on Koopa Beach.” Delightful.

Below, Fallon shares a spring break story about himself and six guys sharing a hotel room and basically getting into shenanigans. Makes you kind of nostalgic for your early 20s, no?

“Spring Breakers” opens nationwide March 22.
