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.
