IN A WORLD obsessed with youth a 69-year-old model has wowed at New York Fashion Week — she also happens to be billionaire entrepreneur Elon Musk’s mum.

Maye Musk strutted the catwalk this week alongside a host of much younger models.

Mother-of-three and grandma hit the runway for Concept Korea and was at nearly every red-carpet event.

She also signed recently with IMG — one of the biggest modelling agencies in the world — and has appeared in magazine for high-end brands like Rag and Bone.

Ms Musk, a veteran of five decades of modelling, began modelling when she was just 15.

She told Hollywood Reporterthat she was surprised by the longevity of her career.

She said: “When I started modelling at 15, I was told it would all be over by 18. So, this is a complete surprise, a happy surprise at 69.”

Ms Musk has three children including Elon, 46, who is the eldest.

She raised the Telsa motors and SpaceX CEO and founder and his siblings alone after splitting from her husband after nine years of marriage.
