The celebrity couple, who married in 2010, are already parents to 18-month-old daughter Lyra.
The new addition will become part of the Dahl dynasty, as Sophie is the granddaughter of legendary children’s author, Roald Dahl. Wouldn’t you just love to have a nose around their family library!
The news of her pregnancy came after the couple were seen at the Harper’s Bazaar awards at Claridge’s earlier this week.
Wearing a loose fitting patterned dress, black tights and flat pumps, the hint of a bump and knowing smile were more than a giveaway.
Congratulations from the MFM team!
