Parents-to-be Heath Ledger and DAWSON'S CREEK star Michelle Williams have swapped their cosy rented apartment for a bigger home in Brooklyn, New York City, in preparation for the arrival of their baby girl.

The roomy house in Boerum Hill said to have set the showbiz couple back $2 million (GBP1.1 million), reports gossip site PageSix.com.

The pair met on the set of Ang Lee's forthcoming romance Brokeback Mountain, in which Australian heart-throb Ledger plays a gay cowboy who has an affair with Jake Gyllenhaal.

Their baby was also conceived during filming.
