Her rep says, “Mother and baby are doing great.”
The 38-year-old actress already has Mia, 13, and Joe, 10, with first and second husbands Jim Threapleton and Sam Mendes.
In her interview with Vogue she said the kids live with her.
“[The children have] always been with me. They don’t go from pillar to post; they’re not flown here and there with nannies. That’s never happened. My kids don’t go back and forth; none of this 50/50 time with the mums and dads – my children live with me; that is it. That is it!”
She also told Good Housekeeping that she loves 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.”
