The couple, who just confirmed they were dating one another last month, hit the stage together in Los Angeles Tuesday night to perform their newest collaboration together, Best Mistake.

The 21-year-old Grande donned a sexy red dress that featured cutouts on our back side and front.

She paired it with a pair of matching red stilettos. Her nails were kept classy with a nude, soft pink color. Big Sean, 26, looked pretty dapper himself as he rocked a black tuxedo and bow tie. The two held hands during the song and at one point of the song and Grande touched Big Sean's chest as he smiled at her. They ended their performance walking off the stage hand in hand.

Take a look at the pictures here.

This was Grande's second performance of the night. She also had a solo number in which she wore a white, sleeveless mini-dress with white fringes and silver sequins along with white heels.

Mary J. Blige, Maroon 5 and Pharrell also hit the stage. LL Cool J served as MC for the evening.

Big Sean and Grande went public after making several songs together and months of playing coy on whether they were really together. Grande revealed that she is still not sure she made the right decision when confirming their relationship.

"I have conflicting feelings about it," she told InStyle magazine. "On the one hand, I feel like I'm growing up and realize my life is my life and some things don't need to be shared. But I'm very spur-of-the-moment, very open with my fans. And if there's a cute pic I like that's a little personal and I want to share it, maybe I will."

A Very Grammy Christmas airs Dec. 5 on CBS. In the meantime, check out Big Sean & Ariana Grande's cozy performance at the iHeart Radio festival from this September.
