The couple, who married in April 2013 after a five month engagement, already have a daughter, two-year-old Dulcie.
The exciting news comes via People magazine, who claim the 33-year-old revealed his wife’s pregnancy news in their Sexiest Men issue.
Meanwhile E! News have also revealed the pair are expecting bub number two. Jamie is yet to comment on the claims.
We bet he can’t wait for the arrival of their new bundle of joy, as Dornan has spoken candidly about his love for fatherhood in the past.
In February, he told Now magazine that fatherhood was “the most joyous thing imaginable. It’s totally changed our lives but only for the positive.”
“I was discouraged by people’s attitude so it was refreshing when we occasionally met people who said, ‘It’s the best thing, you’re going to love it.'” The actor explained.
“I saw a pregnant friend the other night and I was like, ‘Embrace it! Don’t listen to all the people who are down on it, because it’s only good.'”
And this super-dad doesn’t mind putting in the hard yards, either. “I don’t mind getting up in the middle of the night with her,” he said, “although we’re lucky because she sleeps for 12 hours.”
Let’s hope baby number two is just as much of an angel!
