WATCH: GRACE VANDERWAAL Serenades Couples At The Top Of Empire State Building!

Grace VanderWaal painted the town red this Valentine's Day!

The America's Got Talent champion led the lighting of the Empire State Building on February 14 and serenaded soon-to-be married couples who won a contest.

It must have been a memorable night for the couples as 13-year-old Grace sang "I Don't Know My Name" and "Light the Sky" at the top of the Empire State Building - on the 86th floor to be exact!

"Singing for soon to be married couples at the top of the Empire State Building. I just flipped the switch to turn it RED for Valentine's Day. Congratulations to all of the lucky couples," Grace wrote in the caption. Watch her performance below!
