Bosses at fast food chain Chipotle have officially dropped their breach of contract lawsuit against R&B star Frank Ocean.

The Pyramids singer allegedly backed out of a $425,000 (Gbp265,600) deal to sing the theme to an ad for the chain, and when bosses filed suit for the return of their advance, Ocean took to his Tumblr.com account to post a photo of a cheque for $212,500 (Gbp132,800), adding the words "F**K Off" in the memo section.

A spokesperson for Chipotle has now confirmed to Rolling Stone that Ocean has paid up and bosses have agreed to drop the lawsuit. The cheque received was not the one Ocean posted an image of online.

The legal spat began when Ocean pulled out of a deal to record a rendition of Leslie Bricusse and Anthony Newley's Pure Imagination from Willy Wonka & the Chocolate Factory for a Chipotle ad. The firm's bosses eventually asked Fiona Apple to record the track.
