It's a music power couple in training.

After six months of dating and some sexy onstage PDA Ariana Grande and Big Sean finally made their red carpet debut at the Grammy Awards on Sunday.

Grande, who is nominated for Best Pop Vocal Album and Best Pop Duo/Group Performance, told Ryan Seacrest on E!'s red carpet show that she was "so nervous."

"I'm just excited to be here," the 21-year-old "Love Me Harder" singer said. "I never expected to be nominated in, like, my first couple of years of doing this, so it's an honor and I'm very excited. I'm super nervous though."

Fortunately, she had Big Sean, 26, on hand to calm her nerves.

"She's pretty calm, she's cool," the rapper noted of his gal pal. "She says she's nervous, but she handles it great, man."

The stylish duo — who started dating after they recorded the song "Best Mistake" together — were certainly dressed to impress. Grande opted for a white-and-silver Versace number while her beau was clad in Saint Laurent. They make a cute couple, no?
