Congratulations are in order for famed fashion designer Stella McCartney, who is expecting a fourth child. Despite having noted in February that she’s “ready to have a bit of a break first,” the daughter of the famous Beatles musician will be, in fact, adding onto her family with husband Alasdhair Willis.

“Stella loves the idea of having a closeknit family, just like the one she grew up in. She’s a great mum. She has been telling all her friends the good news,” a source close to the designer said.

McCartney’s family currently includes her two sons—Miller, five, and Beckett, two—and three year-old daughter Bailey.
