The two have been linked romantically since August and the singer confirmed their relationship in October

Things are getting steamy between pop star Ariana Grande and rapper Big Sean!

This past Tuesday, the two lovebirds, who were first linked romantically in August, performed together at a taping for the A Very Grammy Christmas concert in Los Angeles. Grande wore a red crop top and matching high-waisted pencil skirt and platform pumps as she sang with her beau on stage.

On Saturday, Big Sean posted on his Instagram two photos of the two getting cozy backstage at the event. One of the pics shows them engaged in a sweet liplock.
