Ariana Grande and Big Sean seem to be falling madly in love. The rapper recently shared an intimate photo of himself and the 21-year-old singer kissing. Grande is wearing a form-fitting red dress and her her hair tied in a signature ponytail, whereas Big Sean is wearing a black tuxedo with a bowtie and a white shirt. The photo is taken backstage during the A Very Grammy Christmas event in Los Angeles on Tuesday. The rapper captioned the picture as, "Me n my Ari."

The duo had performed together at the event and had wooed the crown with their sizzling onstage chemistry. They sang Ariana's latest single "Best Mistake," and will soon be filming its music video. Ariana and Big Sean have been reportedly dating since July, 2014. Though they have never addressed each other as boyfriend and girlfriend in the public, they do maintain that they are special to each other.

"He is one of the most amazing men in the whole world, and that includes my grandfather and my brother," Ariana said to Telegraph about Big Sean. Meanwhile, the rapper said in his interview to Ryan Seacrest, "Everything she has going on is good with her, everything I have going on is good with me, everything between me and her is good, and I'm just going to leave it at that."

Before dating Ariana, Big Sean was engaged to "Glee" star Naya Rivera. They were about to get married, before they abruptly called off their relationship. The reason for their break-up is still not known. Soon after the split, Naya went on to marry actor Ryan Dorsey in a secret ceremony in Mexico.

Meanwhile, Ariana was formerly in a relationship with Jai Brooks. She has also dated "The Wanted" singer Nathan Sykes in the past. The "Problem" singer has been very open about her relationships. She has seldom hidden her romantic life from her fans; however, not many of her relationships have lasted for a long time. It remains to see what future holds for Ariana and Big Sean.
