Rolling Stones Mick Jagger ENGAGED to girlfriend Mel Hamrick less than half his age

Rocker Sir Mick Jagger and long-term girlfriend ­Melanie Hamrick ARE engaged, friends claim.

Melanie, 36, sparked speculation last month by wearing what she laughed off as a “promise ring” from the Rolling Stones singer, 79, on her engagement finger.

But pals say the former ballerina – who met Mick in 2014 and is mum to his eighth child Deveraux, six – admitted on a recent trip to New York they are engaged.
