Hell's Kitchen star Gordon Ramsay might be a nightmare for his chefs, but off camera the 51-year-old is a doting father and family man.

All dressed up in a tuxedo, the TV chef recently posed with his Twin children, Holly and Jack, for their 18th birthday photos. Fans were quick to comment on his daughter Holly, who dressed in a shimmering black body-hugging outfit, cut a stunning figure as she posed between her father and twin brother Jack.

"Gorgeous at 18... So happy and proud for these 2. Continue working hard to follow your dreams love ya both, now can we rent out your rooms please?" the Michelin Star chef shared alongside the sweet snap of his twins.

In the picture, Ramsay and Jack lean in to plant a kiss on Holly's cheeks while the teen poses adorably between them. Keeping with the Great Gatsby-style theme of the big birthday bash, the 18-year-old also rocked golden headband costume jewellery and a generous layer of golden eye makeup.
