Ariana Grande, Big Sean Take Relationship To The Stage! Couple Packs On PDA At KIIS FM Jingle Ball Performance

Ariana Grande and Big Sean are taking their relationship to the stage as they packed a lot of PDA during the KIIS FM Jingle Ball performance at the Staples Center in Los Angeles on Friday night.

"And as they sang 'Best Mistake' together they moved in for a steamy clinch - to the delight of the thousands of assembled fans," MTV said.

The E! News even described Ariana Grande and Big Sean's performance as "steamy."

"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," it said.

A video clip was uploaded by KIIS FM on social media as the couple got cozy together. As they are about to finish their performance, Big Sean grabbed girlfriend Ariana Grande's waist and pulled her towards him as he leaned in for a kiss.

Just as he was about to plant a kiss, Ariana Grande turned her head and teasing the audience in the process.

Earlier, while guesting on "On Air With Ryan Seacrest," Big Sean told the "American Idol" host: "I am going to tell you this: That Ariana is very, very special. She's very special to me. 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."

And feeling is certainly mutual as Ariana Grande told Us Weekly magazine: "He is one of the most amazing men in the whole world, and that includes my grandfather and my brother. I think the world of him, and he's an amazing person. That's kind of all there is to it."

Ariana Grande and Big Sean only dated in August after the rapper separated from "Glee" star Naya Rivera. Ariana Grande also split from The Janoskians' Jai Brooks by the time they got together.
