Hollywood parents-to-be Heath Ledger and Michelle Williams are delighted after discovering their first baby will be a girl.

The DAWSON'S CREEK actress, who met Ledger while filming forthcoming cowboy romance Brokeback Mountain, is expected to give birth in the next few weeks.

While promoting the ANG LEE-directed movie at last month's (AUG05) Toronto Film Festival, the pregnant star revealed their impending bundle of joy was also conceived during filming.

She said, "It's strange to watch the film now because it means so much more to me.

"I met my husband there, the seed of my daughter was born there - it's just really, really powerful."

Williams still insists she is in no hurry to walk down the aisle, despite already calling Heath her husband.

She adds, "I had a few fantasies about a husband and a wedding when I was a little girl. But I'm really happy with things just the way they are right now."
