All week long, ET's Cameron Mathison has been talking GRAMMYs in our brand new Absolut Lime Green Room, and on Thursday, ET's Nischelle Turner caught up with this year's host doing the most, James Corden.

"I couldn't be more nervous. I couldn't sleep last night I was so nervous," Corden admitted. "Nerves are good. You're only nervous when you want to do your best, and I really don't want to mess it up. I don't want to let anybody down."

But as nervous as Corden is to host the GRAMMYs, he might be more nervous for the chance to meet Beyonce for the first time. As a big fan of Queen Bey, Corden has already planned out what he will do should he get the opportunity to introduce himself.

"I will just [kneel]," Corden joked. "And I will hold it until she says I can come up."

While Corden was tight-lipped about any details surrounding Beyonce's performance (which will come on the heels of her pregnancy announcement!), the comedian did confirm that he will not be singing at the event.

"So many people have said to me, 'Are you going to sing at the GRAMMYs?' I'm like, 'You know who's at the GRAMMYs, right?'" Corden explained. "I'm not going to start singing in front of Beyonce and Adele and Bruno [Mars]."

Absolut partnered with the GRAMMYs this year to celebrate the launch of their newest flavor, Absolut Lime. The 59th Annual GRAMMY Awards will air live on Sunday at 8 p.m. ET / 5 p.m. PT on CBS.
