posted by Danny - 

Bruno Mars turned 33 yesterday, and celebrated it backstage before his performance at Bridgestone Arena by "hiring" Ed Sheeran to sing "Happy Birthday" to him -- or so he says on Instagram, where he posted video of Sheeran serenading him while he dug into some birthday cupcakes.

Sheeran also joined Bruno for a duet on the Gingerbread Man's "Thinking Out Loud."
