Supermodel Lara Stone has a little cover girl (or boy) on the way!

The Dutch beauty, 28, and her husband David Walliams are expecting their first child together, Walliams announced on Twitter Nov. 15.

"Some wonderful news. My beautiful wife Lara is pregnant. We are having a baby!" the British comedian wrote. "It is due next year and we both couldn't be happier."

In September, Walliams spoke to British Vogue about his plans to start a family with the world-famous catwalker, who has graced the covers of W and international editions of Vogue, and been the face of campaigns for Prada, Louis Vuitton and more.

"Turning 40 has made me think I should probably have kids soon," he confessed. "By the time they leave school I'll be about 60. I'll be at the school gates waiting for them and it'll be embarrassing because the other kids will ask, 'Is that your granddad?'" (For her part, Stone told Dutch Vogue back in May that a baby will "probably never be as fun [as our puppy] Bert.")

Stone and Walliams began dating in September 2009; they exchanged vows in London eight months later.
