Simon Fuller, former manager of the Spice Girls, has revealed that Eurythmics star Annie Lennox helped the '2 Become 1' superstars to focus on their image and embody stronger personalities. 

'The Fuller Picture: The Simon Fuller Story', which is set to be broadcast on Wednesday (January 15) at 10pm, will see the music mogul talk about Lennox's impact on the iconic girl group:

"Each of the girls knew who they were and in their own way tried to represent it but it wasn't strong enough. and probably the most significant thing that happened was when they met Annie Lennox. I'm not sure this story has ever been told and Annie might not thank me for telling it."

"But I think we were flying to New York and I sort of brought up midway in the flight and said I've just signed this girl group. And Annie was very interested."

Fuller continued: "She said "I want to meet them". Almost directly she was the one who who got them to be louder and more brash and more specific, So Emma who was the sweet cute blonde girl became Baby Spice. She just played it and hammed it up - none of these names actually existed, but Annie gave them focus."
