Kate Winslet, who's knocked up with the next generation of little Rocknroll'ers, proved pregnancy agrees with her with a radiant appearance at the Toronto International Film Festival.

The Oscar-winning actress, who was on hand for the premiere of her drama 'Labor Day' (ironic titles are ironic!), wore a Jenny Packham gown that showed off not just her growing belly, but a whole lot of cleavage.

"I have really been enjoying this pregnancy," the 37-year-old mom of two explained. "It’s been good. I was tired in the beginning, but now it all feels okay."

Winslet is now six months pregnant with husband Ned Rocknroll, who's Virgin mogul Richard Branson's nephew. And the couple certainly has an amazing "how we met" story for their impending little one: They were staying (separately) at Branson's Necker Island resort in 2011 when it caught fire and Winslet carried Richard's 90-year-old mother to safety.
