Ed Sheeran pens track for good pal Sacha Baron Cohen

Ed Sheeran's latest track Brother's Blood will reportedly feature exclusively in new flick The Brothers Grimsby.

The film is Sacha Baron Cohen's latest cinema outing, and it sees the British actor tackle yet another in-your-face character.

This time he plays football hooligan Norman 'Nobby' Grimsby, who turns spy when his secret agent brother Sebastian (Mark Strong) turns up.

Britain's The Sun newspaper reports that Ed's track will be part of the movie, but won't be available to download, nor will it feature on the film's soundtrack. The only way Ed fans will be able to hear the tune is if Sacha plays it on the radio during his promotional duties.

"Sacha and Ed have become big pals over the past few years," a source told the publication.

"During Ed's early days Sacha wasn't really familiar with his work. He had no idea who he was when they were introduced. But they're both creative geniuses and have an obvious connection on that front, agreeing to help each other out where possible."

Ed penned Brother's Blood with long-term collaborator Benny Blanco, who's also worked with Rihanna and Justin Bieber.

The Thinking Out Loud sing was missing from the London premiere of the film on Monday night (23Feb16), but stars such as Ashley Roberts, Annabelle Wallis and Sacha's wife Isla Fisher made sure the star power wasn't lacking.

Before Sacha hit the red carpet in full Nobby costume, consisting of a grey polo neck, blue Y-fronts, black socks, slippers and aviator glasses, he stayed in character as he stopped by The Sun to guest edit the showbiz page.

"He's a good lad," he said of Ed. "Impressive that he chooses not to have a disabled badge on his car despite having ginger hair."
