SIR Mick Jagger has become a father again at the age of 73 with his partner Melanie Hamrick, who – at 29 – is 44 years his junior.

The news of the Rolling Stones frontman’s new arrival was confirmed by his publicist Bernard Doherty.

Sir Mick and Ms Hamrick welcomed a son in New York on Thursday.

A statement said: “Melanie Hamrick and Mick Jagger’s son was born today in New York and they are both delighted.

“Mick was at the hospital for the arrival. Mother and baby are doing well and we request that the media respect their privacy at this time.” The new addition is Sir Mick’s eighth child, and his first with ballerina Ms Hamrick.

The couple began dating after the suicide of fashion designer L’Wren Scott, Sir Mick’s partner of 13 years, in 2014. The rock star has seven children – Karis, Jade, Elizabeth, James, Georgia, Gabriel and Lucas – from previous relationships.

Their ages range from 17 to 46, with his eldest child Karis Hunt Jagger – from his relationship with Marsha Hunt – 17 years older than Ms Hamrick.

He had daughter Jade Jagger, now 45, with his ex-wife Bianca.

Sir Mick had four children with his ex-partner Jerry Hall – Elizabeth, 32, James, 31, Georgia, 24, and Gabriel, 18. He also had a son, Lucas, 17, following a brief relationship with Brazilian model Luciana Gimenez. Their liaison ended Sir Mick’s 22-year-relationship with Hall, who is now married to media mogul Rupert Murdoch.

Sir Mick has five grandchildren and became a great-grandfather in May 2014.
