Let's just call Ariana Grande and Big Sean showstoppers!
Things got pretty steamy onstage Friday night when the young Hollywood couple surprised fans with a duet performance of "Best Mistake" at KIISFM's Jingle Ball.
Halfway through Grande's set, the now Grammy-nominated singer invited her boyfriend to perform "one of my favorite songs." What came next was a sexy number that proved these two are still going strong.
In video captured by KIISFM, the two singers get extra close as they finish the lyrics to their hit single.
As Big Sean grabs his girlfriend's waist (or dare we say butt), he leans in for a kiss. But Grande innocently turns her head the other way. Aww, young love.
