The Queen is preparing to host her family for the first time for Christmas at Sandringham this year, but she also marked a milestone occasion on Wednesday.
Camilla, 77, shares her children, Tom Parker Bowles and Laura Lopes, with her first husband, Andrew Parker Bowles.
Food critic and author Tom turned 50 on 18 December and in an interview with The Telegraph, he said he is "planning a couple of lunches to celebrate".
The writer shares two children with his ex-wife and fashion editor, Sara Buys – Lola, 17, and Freddy, 14.
He has written a number of cookbooks, with his most recent, Cooking and the Crown, looking at recipes ranging from Queen Victoria to King Charles' reigns.
In an exclusive chat with HELLO! back in October, Tom revealed that he has overhauled his lifestyle ahead of his 50th birthday.
The author shared that he is drinking and eating less and doing Pilates classes.
"Everyone else is 20 and toned and chiselled," he said of his fellow Pilates attendees. "Sometimes I'm the only bloke there, so I sit in the corner."
