Steve and the Team GB rower shared the happy news on Instagram this afternoon.
The naturalist made the announcement by posting a snap of Helen’s blossoming baby bump, as well as a photo of himself gazing at two birds.
He captioned the photo: “On the boat with my three favourite people; seems this summer we’ll have some wee ones of our own… @helenglovergb.”
Meanwhile, the two-time Olympic champion shared the same post on her Twitter account, which read: “Soooo…The biggest adventure of our lives.. 2 little [chicks] of our own arriving this summer!!! @backshall.steve.”
