During an appearance on 'The Ellen DeGeneres Show' Friday (April 5), Kellie Pickler revealed that she'll be competing to a personal song during next Monday's (April 8) 'Dancing With the Stars.' The theme of the episode is "Most Memorable Year," so the 'Tough' singer chose 2011, the year she married Nashville songwriter Kyle Jacobs.

"My husband is actually going to be performing our wedding song that he wrote," Kellie told her buddy, Ellen. Kyle will be joined by the 'Dancing With the Stars' house band to perform 'Say I Do,' while his wife and her dancing partner, Derek Hough, dance the rumba!

"It's going to be an 100-percent emotional moment, and I'm just hoping I can keep it together," Kyle admits. "Kellie's doing so well on the show, and she's having so much fun. The fact that she's dancing to this song, our song, means so very much to both of us ... it honors the love that we have so much."

Ellen also asked the former 'American Idol' contestant how Kyle feels about seeing his wife dancing cheek-to-cheek with Derek each week, to which she responded, "My husband knows he's always going to get the last dance."

See the performance on 'Dancing With the Stars' Monday (April 8) at 8:00 PM ET on ABC.
