US rapper Kanye West has revealed details of a surprise collaboration with Killers singer Brandon Flowers.

The pair unexpectedly worked together on a song when Flowers and 30 Seconds to Mars’ Jared Leto “stopped by” the rapper's studio recently.

Writing about the collaboration on his blog, West said: “I played them some of the new Jeezy beats and before everybody bounced Brandon hopped on the keyboard and I hopped on the MPC.

“Shit was dope.”

West also posted a picture of himself alongside Leto and Flowers, who was wearing a diamond encrusted shirt by Dries Van Noten.

“Oh and yes those are Swarovski crystals on Brandon’s shirt,” West wrote.
