All they need is mistletoe! Ariana Grande and her boyfriend Big Sean got cozy at the 2014 A Very Grammy Christmas Concert in Los Angeles on Tuesday, Nov. 18.

Quietly dating since August, the couple took the stage together at the Shrine Auditorium in a star-studded event that also included Pharrell Williams, Mary J. Blige, Tim McGraw, and Adam Levine. The festive show will air on CBS on Friday, Dec. 5. 

Grande, 21, was holiday-ready for the concert, donning a slinky red dress and red heels for her performance with her rapper beau. She later slipped into a white fringed minidress with sparkling silver sequins. 

Big Sean, 26, looked dapper in a black tuxedo with a white collared shirt and a black bow tie. The "Paradise" performer had cute moments with his lady onstage, as the pair gazed into one another's eyes, held hands, and pressed up against each other. 

The two musicians first hooked up this past summer following high-profile breakups. Big Sean split from his then-fiancée, Glee's Naya Rivera this past April, who went on to marry model and actor Ryan Dorsey just three months later. Grande broke off her on-again, off-again relationship with comedian and singer Jai Brooks in August, before finding her new man. 

"It's gone from 0 to 60 fast," a source told Us Weekly earlier this fall about the couple's relationship, adding that there was "chemistry immediately" between the two. 

The "Love Me Harder" singer finally confirmed her coupling last month, when she told The Telegraph that she is dating Big Sean and called him "one of the most amazing men in the whole world."
