Unique name Mick Jagger gave his eighth baby

Sir Mick Jagger appears to have named his newborn son Deveraux Octavian Basil Jagger.

A photograph of the baby, Jagger's eighth child, appeared on an Instagram account under the name of Elizabeth Jagger, one of the Rolling Stones rocker's other children.

The caption read: "My beautiful baby brother Deveraux Octavian Basil Jagger."

Basil was the first name of Jagger's late father, who died in 2006, although he was known to others as Joe.

Jagger became a father again at the age of 73 on December 8, with his partner Melanie Hamrick, 29, the Daily Mail reports.

Elizabeth, commonly referred to as Lizzy, is followed by more than 50,000 people on her social media account, although it is not verified.

Jagger, who is a great-grandfather, has six other children as well as Lizzy and his one week-old son - Karis, Jade, James, Georgia, Gabriel and Lucas - from previous relationships.

Their ages range from 17 to 46.

It is understood he flew 3,500 miles from London to New York in a last-minute dash to be by Hamrick's side for the birth.

A statement released on behalf of the couple 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."

Jagger is understood to have given Hamrick a $150,000-a-year maintenance deal to help the ballerina raise their child.

He is also believed to be helping the New Yorker find a home in the US to raise the boy.

The $150k will be paid until the child is 18, with school fees also paid for. After secondary school a trust will help cover further education and expenses, which could be as much as £500k.

Even though the pair are not planning on getting married, they plan to co-parent given his hectic work schedule.

Jagger has five grandchildren and became a great-grandfather in May 2014 when Jade's daughter Assisi gave birth to a baby girl.

The new addition is his eighth child, and his first with Hamrick.

The baby news comes six months after his bandmate Ronnie Wood's wife Sally Humphreys gave birth to twin girls, just two days before Wood turned 69.
