A photo of Mick's newborn baby appeared on Elizabeth Jagger's Instagram account, and in the caption Elizabeth introduced his name. "My beautiful baby brother Deveraux Octavian Basil Jagger," she wrote, according to reports, but the picture has since been deleted. Elizabeth is one of the Rolling Stones rocker's other children.
Basil was Mick's late father's first name, though many knew him better as Joe. Octavian means "born eighth" in Latin, which is all too perfect considering he is Mick's eighth child. He welcomed Deveraux with girlfriend Melanie Hamrick, 30.
E! News has reached out to a rep for Mick for comment.
Mick and Melanie reportedly began their relationship in 2014, after Mick's longtime partner L'Wren Scott died. They've kept their relationship private, but his rep announced the ballerina's pregnancy and their son's birth.
"Melanie Hamrick & Mick Jagger's son was born today in New York and they are both delighted," the singer's rep told E! News. "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 rocker has seven other children, four daughters and three sons ages 18 to 47, with four exes. He also has five grandchildren.
Congratulations again to the happy couple!
