Bruno Mars celebrated his 33rd birthday in unforgettable fashion backstage at Nashville’s Bridgestone Arena, where Ed Sheeran made a surprise appearance. Mars jokingly said he “hired” Sheeran to sing “Happy Birthday” to him, and the British singer delivered—with guitar in hand and a cheeky personalized twist to the lyrics.
The moment was captured in a video posted to Mars’s Instagram. He wore a gold party hat and enjoyed cupcakes while Sheeran serenaded him, singing, “Happy birthday, dear two-time Super Bowl–performing Bruno.” After the first round, Mars grinned and demanded a second take. Sheeran laughed and sang it again, to the crowd’s delight backstage.
The moment highlighted the strong friendship between the two global stars. They had teased fans before about working on music together, and this surprise performance added another charming chapter to their bond. Fans flooded the comments with praise for the duo’s chemistry and Sheeran’s lighthearted energy.
After the party, Mars continued his 24K Magic tour, while Sheeran remained on his ÷ (Divide) tour. Though brief, the birthday serenade stood out as one of the most wholesome moments shared between two of pop’s biggest names. It was a reminder that even megastars enjoy a good laugh—and a song—on their special day.
