Just call him a little Rocknroller.

Kate Winslet welcomed her third child, a son named Bear, on Saturday, Dec. 7 at an NHS hospital in Sussex County, U.K, her rep confirms to PEOPLE.

“Mother and baby are doing great,” the rep says.

This is the actress’s first child with husband Ned Rocknroll , whom she wed last December. The couple announced that they were expecting in June.

Winslet, 38, who has two children — Mia, 13, and Joe, 10 this month — from previous marriages to Jim Threapleton and Sam Mendes, admitted that she wanted to expand her family, telling InStyle in 2006, “I’m hoping to have more kids. I don’t know whether one or two. Oh, God, I would love to have more.”

The Oscar winner, who admits she’s “not strict” but also not a pushover as a mom, told Good Housekeeping the following year that she enjoyed her hectic mornings with her children.

“I love the routine. I love getting up in the morning and getting breakfast and packing lunches and doing the school run. Those things are really important to me,” she said. “My kids are my whole world.”
