Stella McCartney, 38, expressed interest in adding to her clan last February.
"I'm kind of interested in having more children," she told the UK's Evening Standard last year. "Though right now I feel I've only just stopped having them, so I'm ready to have a bit of a break first."
Looks like Stella McCartney won't be getting that long of a break. She's reported to be due later this fall.
The 38-year-old designer's family unit already consists of sons Miller, 5, and Beckett, 2, and a daughter Bailey, 3, with British publisher Alasdhair Willis.
"She's a great mum. She has been telling all her friends the good news," a source gushed to the UK Daily Mail.
Congrats to the mommy-to-be!
