For all the Gleeks ('Glee' freaks) out there, the cast of the popular FOX series will be performing Lady Antebellum's 'Need You Now' for their special Super Bowl-themed show on Sunday (February 6), following the big game.

The members of Lady Antebellum have reached new heights and been places with the song that they never would have thought possible. "The response from the get-go was so big," Lady A's Charles Kelley tells The Boot. "I remember even having some conversations with the label where they said, 'Oh, I hope they don't get offended by 'I'm a little drunk and I need you now.' I said, 'But, that's honest! We're talking about country radio, right? It's storytelling.' It's been a career song for us for sure. We thought 'I Run to You' was our career song, but honestly, after 'Need You Now' came out and what it's done for us, it's been really, really, really huge for our career. We're proud of it."

Lea Michele, who plays Rachel on 'Glee,' leads the cast in the song, while other hit tunes to be featured on the episode include Michael Jackson's 'Thriller,' Destiny Child's 'Bills, Bills, Bills' and Katy Perry's 'California Gurls.'

Lady A will play a part in pre-Super Bowl festivities, as well. Their song 'Stars Tonight,' also from the 'Need You Now' album, will kick off the official NFL pre-game Westwood One radio coverage of Super Bowl XLV on Sunday. A special version of the song, mixed with highlights of the Pittsburgh Steelers' and Green Bay Packers' winning seasons, will be aired on more than 640 radio stations.

Lady Antebellum, who just received three ACM nominations this week, will be seen performing next on the Grammy Awards, where they are up for six nominations including Record of the Year, Album of the Year and Song of the Year, as well as Best Country Album and Best Country Song. This years Grammy Awards will air live from Los Angeles on February 13 at 8:00 PM ET on CBS.
