"She was so wonderful and so happy and they looked great together. I was thrilled."

Big Sean also gave his lady his full attention while walking the red carpet at the Grammys.

When being interviewed by AJ Holloway of Extra TV, Big Sean made it clear it was Ariana's big night.

"I saw her dress and how beautiful it was. I decided I just wanted to let her do her thing. I mean, it's her night."

As far as it being the couple's first time at a huge event, Big Sean said, "I didn't even think of it like that."

After months of playing coy on whether they were actually a couple, Ariana and Big Sean aren't afraid to show each other love on social media these days.

Ariana even opened up to fans and let them know she likes to wear his clothes.

She shared a picture of herself rocking a Tupac t-shirt Feb. 10 and added the caption, "when u look cuter in his clothes than he does"
