The couple confirmed their relationship this past October when Ariana gushed about her beau to The Telegraph. "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,” she said.

Big Sean -- who started dating Ariana after breaking off his engagement to Naya Rivera -- also gushed about his famous girlfriend in a recent interview with Billboard magazine. "She's super cool -- the coolest," he said of the "Problems" singer. "Ever since, we've been friendly, hung out once in a while, and it just evolved. I respect her -- so I don't think I should talk about it."

The two seem to be having lots of fun together. Most recently, the "Bang Bang" singer posted a pic of her with her man at dinner, writing: "FYI, he stood up on his chair & started singing stevie wonder at the top of his lungs after this photo was taken and i ran to the bathroom and hid (not actually)."
