Sam Branson has revealed he and his wife are expecting a second baby.
The 31-year-old, who is the son of Virgin tycoon Sir Richard, married Isabella Anstruther-Gough-Calthorpe in 2013. He broke the news of the pregnancy at the foot of the Matterhorn mountain, which he climbed two years ago.
He told the Press Association: "I would absolutely love to do it (climb the mountain) again, but I've got a little baby and another baby on the way, and I've already climbed it once and got to the summit, and so weighing it up I just need to be a little bit more sensible."
The couple already have daughter Eva-Deia Branson, who was born in February 2015.
Isabella, 36, an actress and model, is understood to be five months pregnant. She is the half-sister of Cressida Bonas - a former girlfriend of Prince Harry.
Sam is taking part in a charity challenge that involves hiking, swimming and cycling from the foot of the Matterhorn in Switzerland to the summit of Mount Etna in Sicily.
The Virgin Strive Challenge is raising £1.5 million for Big Change - a foundation set up by Sam and his sister Holly.
