Lady AntebellumLady Antebellum are thrilled and nervous about performing on Sunday night's Grammy Awards, where they are up for Best Country Performance by a Duo or Group With Vocals and Best Country Song for 'I Run to You.'

"I think now that we have a performance slot, we feel a little pressure to put on a good performance," Lady A's Charles Kelley tells OK Magazine. "It's going to be not just the country market likely listening to us for the first time and this will be their introduction to our music and seeing us live, so we want to nail it. With the success of 'Need You Now' through the roof, we feel like this could be our chance to take it to the next level if we have a good performance."

The group is set to perform some time very close to the Grammy performance of Hillary Scott's hero, Beyonce. "We're before or after ... and it's really scary no matter how you shake it," explains Hillary.

While they're excited about seeing Beyonce at the Grammys, there are also a few other famous faces they'd like to see on stage. "Black Eyed Peas are always fun to see," says Charles. "And the Zac Brown Band is a great country band that we're excited to see ... and Taylor Swift, we're friends with her."

Prior to Sunday night's big show, Lady Antebellum will be performing at the all-star tribute to Neil Young as the 2010 MusiCares Person of the Year. They'll sing 'Only Love Can Break Your Heart' from Neil's 1970 album, 'After the Gold Rush.'
