Stella McCartney & Claudia Schiffer On Their School Run

Stella McCartney was seen with her friend Claudia Schiffer during their school run in West London on Friday (September 17).

The designer's 5-year-old son Miller goes to the same private school as the supermodel's kids. Earlier Claudia was seen with her son Caspar, 7.

Stella is expecting her fourth child with husband Alasdhair Willis. They also have Bailey, 3, and Beckett, 2. She once talked about her dilemma on sending her kids to private school.

It's one of my biggest internal struggles, the fact that my kids are going to a posh school. It freaks me out."
