Ariana Grande, Big Sean gets 'cozy' during performance on stage

Ariana Grande and Big Sean recently got cozy on stage while performing a duet of 'Best Mistake' at KIISFM's Jingle Ball.

The Grammy-nominated singer got extra close with her rapper boyfriend as they finished the lyrics to their hit single, E! Online reported.

Sean apparently grabbed Grande's waist as he leaned in for a kiss but Grande turned her head the other way.

Grande started dating the rapper few months ago.
