While you expect a great variety of performances at the ACM Awards, there’s one special occurrence you’d never anticipate seeing on the ACM stage: a wedding. Well, prepare to have your expectations blown away this year! Martina McBride and Train frontman Pat Monahan are due to perform McBride’s latest single ‘Marry Me‘ while a couple actually gets married on stage.

The New Jersey couple sealing their vows on the ACM stage on April 1 were hand-picked by McBride due to their inspirational story. Christina Davidson and her fiance Frank Tucci both lost their spouses in 2009 and later met while attending a support group for young widows and widowers, arranged by Davidson herself. Both single parents, the two solidified their friendship as they grew and learned together.

McBride covered Train’s ‘Marry Me’ for her October 2011 record, ‘Eleven,’ as a duet with Monahan, singling the track earlier this month as a follow-up to her Top 5 single ‘I’m Gonna Love You Through It.’ The songstress is up for the Female Vocalist of the Year award at this year’s ACMs.

In addition to McBride and Monahan’s matrimonial number, other top country performers like Miranda Lambert, Jason Aldean, Tim McGraw, Kenny Chesney and Toby Keith will be hitting the ACM stage to perform their chart-toppers and recent singles. Reba McEntire and Blake Shelton will do the hosting honors for their second consecutive year. The live telecast of the entire event will be filmed at Las Vegas’ MGM Grand Garden Arena and will air on CBS Sunday, April 1 beginning at 8PM ET.
