Geri Horner says she "looked like a drag queen" when she was in the Spice Girls

She said: "Oh my God, towards the end of the Spice Girls, the time I got Billboard Awards, I was looking like a drag queen.

"Do you know what it is? It's the Elton John effect. You look at Elton John's career and he always tried to get bigger and bigger and bigger. His glasses were getting bigger - you try to outdo yourself, and I think that's what happens. You try and up the ante all the time.

"By the time I got the American, I can't remember when exactly, but I was in some sort of American flag outfit. I looked like a man in drag."

The 44-year-old singer really loved filming the band's movie 'Spice World' but admits it wasn't good for her waistline.

She added to Billboard: "When it came to 'Spice World', however many years later, it came to casting and we were going through pictures and I was like, 'Let's pick him, I saw him in Hamlet.' It was brilliant to have that caliber of actors to be in our funny movie.

"When you have an idea in your head and then you see it come to life - that was just amazing. But I have to say, I think filming movies are fattening because you have craft services. You're about to go on camera and you want to look your best, but then there's a tower of donuts or something. I just remember putting on so much weight filming Spice World. I was so bloated by the end."
