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.

Three weeks ago, the Detroit emcee Instagrammed a snapshot of himself sporting a black Tupac tee under a green camouflage coat with a matching black snapback.

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."

As the "Blessings" rapper gets philosophical on the importance of patience, a romantic shot of him embracing the "Break Free" hitmaker and giving her a passionate kiss is shown. "Patience is the ability to accept trouble, suffering, delay without getting upset," he says. "I feel like if you can master patience, you can master anything... It's hard to realize this when things aren't coming fast enough - whether it's a check, a job, a loan, a dream, a goal - it all takes patience."

Big Sean elaborated more on patience via Twitter:
