In a tweet Jones said that his wife, photographer Rodene Ronquillo, had given birth to their son Stenton David Jones earlier in July.
David Bowie’s son Duncan Jones has announced the birth of his child six months after the musician’s death.
Their son is named in honour of Bowie’s family – David in tribute to his grandfather and Stenton after David Bowie’s own father, Haywood Stenton Jones.
Film director Jones, 45, is Bowie’s eldest child, and the only child from his marriage to his first wife, Angie.
