American Idol contestant Layla Spring got the surprise of a lifetime during the show’s finale!

Much to their amazement, LeAnn joined the sisters halfway through their performance!

“I was honored to be asked by American Idol to surprise Layla and Dyxie Spring on the season finale,” LeAnn said in a statement.

She added, “The American Idol team can sure keep a secret! The sweethearts had no idea; it felt like a surprise birthday party! The two of them bring so much joy to the world, and I hope I was able to give them a little of it back.”
