Former Spice Girl, and not to mention only one to go successfully solo after the Spice Girls, Mel C thinks the boys from 1D are great but wants them to stay real...

“They seem to be breaking America, which we were lucky enough to do. My advice would be just enjoy it, because so often with success like that, it's over so quickly … With pop bands, [fame] is often so short-lived that you have to take every opportunity that you can, and it is hard. I would say that you have to rest as much as you can. I think it's harder for boys, as well, but there's lots of evidence that they like a bit of a party. There's no time for hangovers, really. It can be difficult, but I have no sympathy.”
