Carine Roitfeld has become a grandmother.

The former French Vogue editor's daughter Julian Restoin Roitfeld has given birth to a daughter with boyfriend Robert Konjic although the name of the baby has not yet been announced.

Harper Bazaar's Derek Blasberg tweeted yesterday (16.05.12): "Congratulations to proud Momma@RestoinRJulia! (And thus, the chicest grannie ever: Carine Roitfeld!) Can't wait to meet the beautiful baby! (sic)"

Next Models publicist Katy Moseley confirmed the news in an official statement, saying: "We are delighted to confirm that Julia and Robert have had a healthy baby girl. Both mother and daughter are doing very well and resting at home."

Julia announced in November that she and model Robert were expecting a baby and recently posed semi-nude for i-D magazine to show off her bump in a shoot styled by her mother.

Julia said at the time: "I loved that my mum dressed me sexy like that. Pregnancy's a moment in a woman's life when it's really important to still feel seductive."

Carine previously revealed she has no plans to be labelled 'grandma' and would prefer to be called 'Madame'.
