The romance between Ariana Grande and boyfriend Big Sean, who made their red carpet debut as a couple at the 57th Annual Grammy Awards on Sunday, seems sweeter than ever, as they now wear each other's clothes.

Meanwhile, Big Sean released his "Patience" footage, the latest in a series of video blogs on his life reflections, featuring none other than his girlfriend Grande. The clip opens with a quote by Joyce Meyer that reads, "Patience is not simply the ability to wait -- it's how we behave while we're waiting."
