This the first child for Dunn and her boyfriend of five years, who are yet to announce the name of their bundle of joy.
The happy news comes almost exactly a year after Dunn was crowned Model of the Year at 2008's British Fashion Awards. She was famously scouted in Primark, and went on to pick up a string of prestigious campaigns, from Topshop to Benetton and Gap.
A catwalk favourite, she even took to the runway at seven months pregnant for Jean Paul Gaultier. Now the rumour mill is rife with whispers that Dunn has already been approached to sign up her baby for modelling gigs, too.
Congratulations to the new parents!
