After performing at the iHeartRadio Music Festival Saturday night, the "Lego House" singer and One Direction member kept the fun going as they headed to XS nightclub at the Encore resort inside Wynn Las Vegas.
While enjoying the music of David Guetta, Sheeran delivered a giant kiss on Horan's cheek before hopping on the stage to dance.
"Turn down for ?" Horan tweeted after his busy night out.
The innocent kiss speaks volumes to fans who have wondered how the musicians' relationship stands today. In a recent interview with the Howard Stern Show, Sheeran implied that the One Direction member stole his girlfriend.
