IT’S common knowledge that the birthday boy always gets his own way on his special day.

That’s how Bruno Mars got away with posting a video clip to Instagram of Ed Sheeran serenading him with a birthday song, along with the caption, “You know you’ve made it when you can hire Ed Sheeran to sing you Happy Birthday #Extra Forever!#HappyBrunoMarsDay!”

In the video, Mars is wearing a paper party hat, surrounded by gold balloons and tucking into a plate of cupcakes bearing the letters of his name. Sheeran obediently sings to him, replacing the lyrics of the birthday song with, “Happy birthday to three-time Super Bowl-performing Bruno.” Mars nods in approval and commands imperially, “Again.”

The video was recorded backstage at the Bridgestone Arena in Nashville, Tennessee, where Mars was holding a concert as part of his 24k Magic World Tour. During the show, he and Sheeran performed the song “Thinking Out Loud” together on stage.  (SD-Agencies)
