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 singer’s other children.

The caption read: “My beautiful baby brother Deveraux Octavian Basil Jagger.” The picture was later removed from the account.

Basil was the first name of Mick Jagger’s late father, who died in 2006, although he was known to others as Joe. Octavian is Latin for ‘born eighth’. The musician became a father again at the age of 73 on 8 December, with his partner, ballerina Melanie Hamrick, 29.

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.

Jagger and Hamrick began dating after the death of Jagger’s partner of 13 years, fashion designer L’Wren Scott, in 2014.
