Celebrity baby names: Petal
Jools told parenting magazine Gurgle: 'They all have more than one name because I couldn't decide. I'm not sure where Petal Rainbow came from - apparently it's a My Little Pony! I wanted to call her Rainbow but Jamie told me to calm down.'
The couple also welcomed son Buddy Bear Maurice, in September 2010, and River Rocket, in August 2016.
