Kate Winslet's children have completely transformed her life.

The 'Labor Day' star, who is pregnant with her third child, debuted her baby bump at the Toronto International Film Festival on Saturday (07.09.13) as she promoted her new movie and gushed about motherhood.

She said: "I feel completely great. It's such a pleasure to be able to be here and still be permitted on an airplane and talk about a film that I'm proud to be a part of."

She also told People.com: "Being a parent turns you inside out. It completely transforms your life and, of course, your children are your absolute everything."

The 37-year-old actress - who has a 12-year-old daughter, Mia, from her first marriage to Jim Threapleton, and a nine-year-old son, Joe from her second marriage to director Sam Mendes - announced in June that she and her third husband Ned Rocknroll are expecting their first child together.

The Oscar-winner, who tied the knot with Ned, who is the nephew of Sir Richard Branson, in a secret ceremony in December, previously revealed she was eager to have at least one more child.

She said: "I'm hoping to have more kids. I don't know whether one or two. Oh, God, I would love to have more."
