A lock of Sir Mick Jagger's hair is set to go under the hammer next month (Jul13) after it was discovered by a relative of his former girlfriend.

Model Jean Shrimpton dated the Rolling Stones star during the 1960s and her grandmother held onto the clipping after Jagger got a trim at her family's farm.

Now fans can get their hands on a piece of the hitmaker's luscious locks when the off item goes up for sale at Bonham's Auction House in London on 3 July (13).

The star's strands are expected to fetch at least $2,300 (£1,484), with proceeds from the sale going to the charity Changing Faces, which provides financial support to those with physical disfigurements.

Selling off Stones' stars' hair has become a new trend in Hollywood - a clipping of his bandmate Keith Richards' hair recently sold for $1,400 (£903) at auction.
