Big Sean Calms Ariana Grande’s Nerves at 2015 Grammy Awards

Ariana Grande and Big Sean, the "it" couple of the moment, hit the red carpet at the 57th Annual Grammy Awards on Sunday (Feb. 8) looking stunning. While Sean, who put on an amazing show at the House of Blues in Los Angeles the night before, was decked out in Yves Saint Laurent, Ariana shined in a silver-and-white Versace gown.

Besides talking about their couture digs, the pair chatted with E! News' Ryan Seacrest. "I am nervous," Ariana told Seacrest. But the rapper, who has been at the ceremony before, was cool as a cucumber. He confirmed that he has her back and that she's been pretty calm to say the least.

This is the first Grammy Awards for the pint-sized songstress, who is also nominated. She will face off against Miley Cyrus, Katy Perry, Coldplay, Ed Sheeran and Sam Smith for Best Pop Vocal Album for 'My Everything,' in addition to being a runner-up for Best Pop Duo/Group Performance for 'Bang Bang!'

Besides attending, Ariana will also hit the Grammys stage. She is said to be taking part in a Stevie Wonder tribute on top of her own solo performance. Tune in to the 57th Annual Grammy Awards live on CBS at 8PM EST.
