Who is Bear Grylls' wife?
Bear Grylls is married to Shara Grylls, née Cannings Knight.
As well as being a mum to her and Bear's three sons, Jesse, 19, Marmaduke, 16, and Huckleberry, 13, Shara is an author and has written two books about marriage.
The 48-year-old began her career as a writer in 2006 when she published her first book, Marriage Matters, which is a "sparkling collection of wise and witty sayings on marriage" and contains various nuggets of wisdom given to Bear and Shara Grylls when they got married.

Six years later, she released a second book, Never Stop Holding Hands, which was inspired by advice given by an elderly couple to the pair.
Bear and Shara have been married since 2000
Shara met Bear - real name Edward Michael Grylls - just a few months before he left to climb Mount Everest when he was running around naked on a beach in Scotland on New Year's Eve.
Days later, Bear became the youngest Briton to reach the summit of Mount Everest when he was just 23. The pair went on to tie the knot in 2000 and immediately enrolled in a marriage course. He told Piers Morgan in a 2014 interview: "We figured that if this was the most important thing we were ever going to do, we should do everything we could to stop it breaking in the first place."
The pair welcomed their three sons in 2003, 2006 and 2009.
Chatting to HELLO! last year, Bear revealed that his three boys have taken after him in their love of the outdoors. "All the boys are so different, and like all teenagers, they change their mind pretty often, but they have a great spirit and have grown up to love the outdoors," he said. "Scouts has been amazing like that for so many families. Encouraging friendships and a respect for nature. Those things are important."
