MELANIE CHISHOLM is scuppering plans for a Spice Girls reunion because she thinks her solo career is more important, according to the girl band's creator Simon Fuller. Fuller, who founded the five-piece in 1994, claims Victoria Beckham, Geri Halliwell, Mel B and Emma Bunton are keen to reunite - but Mel C is refusing. He says, "Mel C thinks her solo career is bigger than the band, which is just not the case. "She needs to wise up and realise a reunion would be amazing for everybody concerned." But Fuller believes if the group do return, it will be short lived. He adds, "The Spice Girls will come back with a big bang. They''ll do a whirlwind tour for six months and they'll be gone again."
