Mel B fools around on stage

Mel B pinches her fellow Spice Girls' butts on stage.

Scary Spice is so excited about being reunited with her band mates - Emma Bunton, Mel C, Victoria Beckham and Geri Halliwell - she can't help but show her affection in her trademark outrageous fashion.

Emma said: "Mel B has got this thing at the moment for pinching all of our bottoms - it really makes us giggle!"

The blonde star, also known as Baby Spice, admitted there is one major disadvantage to not performing as a band for nine years - she keeps forgetting the lyrics to their famous songs.

Emma added on the official Spice Girls blog: "With each show I'm getting more and more confident with singing live but during 'Mama' the other day I got so carried away looking at the video playing behind us of all the mother and babies that I forgot the lyrics!"

The girls are currently in Los Angeles for the latest leg of their 'Return of the Spice Girls' tour.
