Gwen Stefani - Daisy Lowe
OK. So you're obviously familiar with Gwen Stefani, No Doubt frontwoman and Grammy-winning superstar, and you might know of English fashion model Daisy Lowe, daughter of post-grunge alt-rocker Gavin Rossdale, a.k.a. Gwen Stefani's husband.
But there's a lot of surnames flying around here, so you might not have made the connection that Stefani is Daisy's step-mother, by way of the Bush frontman.
