Producer Mark Ronson was paid a reported £1million for a 45 minute performance at a private birthday party, it's been claimed.

Ronson was a surprise guest at the Cotswolds party, held to mark the 21st birthday Freya Dawson, the daughter of haulage millionaire Peter Dawson.

According to the Mirror newspaper, Ronson sang happy birthday to a “shocked” Ms Dawson before performing with his band.

Ronson's set included his cover of The Zutons 'Valerie', which he often performs with Amy Winehouse.

The party is said to have cost Mr Dawson £4million and was described by one guest as “the type of thing reserved for royalty.”

A spokesperson for the Dawson family paper said he was unavailable for comment because “they are extremely busy still clearing up after the party." (@Music)
