"I love the word luna. I know it's a girl's name, so maybe for the next baby," Posh told a Spanish magazine.

Luna Lovegood was one of the new characters introduced by JK Rowling in Order Of The Phoenix. Luna is the Spanish word for moon.

The Beckhams are expecting their third child in March. The baby's going to be a boy, so he won't be called Luna.

Posh told the magazine that she hasn't chosen a name for the new baby.

"We want to wait and she what he is like," she said.
