Ed Sheeran had to cancel his concert in Las Vegas on Saturday at the last minute due to technical and safety issues, but his extra time was put to good use. He shared an Instagram video yesterday of himself surprising an unsuspecting couple by performing a new song called "Magical" during their wedding at the famous Little White Chapel. The shocked bride and groom got emotional and held each other as Sheeran (and four backup vocalists) serenaded them. The couple then hugged Sheeran before being pronounced husband and wife and sharing a kiss. When they signed the wedding paperwork, Sheeran added his name as a witness. "Crashed a wedding, this is Magical," Sheeran captioned his post. The song appears on his upcoming album, Autumn Variations, which drops September 29th.
