“You know you’ve made it when you can hire Ed Sheeran to sing you Happy Birthday #ExtraForever! #HappyBrunoMarsDay!” Mars captioned a clip of Sheeran, 27, singing.
In the video, which was shared on Instagram, Sheeran can be heard belting “Happy birthday to three-time Super Bowl-performing Bruno,” as Mars munched on a cupcake assortment while wearing a gold party hat.
As the song came to an end, Mars demanded Sheeran start over, which he did without any objections.
Mars was in Tennessee as part of his 24K Magic Tour, which kicked off in September. In August, the Grammy Award winner revealed he added singer Ciara to his tour after Cardi B dropped out to stay with her newborn daughter Kulture Kiari.
