Sir Paul McCartney's family has lots to celebrate these days.
At the weekend, his daughter Mary got married, and now her sister Stella is expecting a fourth child with husband Alasdhair Willis, according to reports.
The pair are already parents to two sons, five-year-old Miller and two-year-old Beckett, as well as daughter Baily, three.
Earlier this year, the fashion designer revealed that she hoped to add to her brood.
"I'm kind of interested in having more children," she said in February. "Though right now I feel like I've only just stopped having them, so I'm ready to have a bit of a break first."
