As the girls gear up for the upcoming Spice Girl Reunion, it seems their in a mad rush to see who can be the skinniest. Posh will probably end up with that title, but Ginger and Scary are vying for the title of most toned -- each is showing off hot new six packs, despite being working mums with busy schedules. And Mel B is a new mum -- she only gave birth to daughter Angel in April.

Mel B owes her svelte new body to hard work, according to the Daily Mail -- she trains for 90 minutes six days a week and does Capoeira and yoga. In addition, she spends her days and nights practicing dance routines for Dancing with the Stars and the upcoming tour.

I think she looks awesome. What do you think?
