Sensibility.

"Sugababes' Heidi Range has said that she has no plans to go solo because it would be too "tough".
The popstar has reportedly been offered the opportunity to forge a career away from the band, but turned it down because she isn't sure she could handle the pressures of working on her own.
Range told the Daily Star: 'I like ­making music but my ambitions are to do well with the band.'
'It’s too tough out there as a solo star on my own. I have seen so many fall and it isn’t nice'"

Heidi, you are just the best. That's the most sensible thing I have ever heard a member of a group say. Going solo almost never works, so why risk it? Although I would LOVE a Heidi solo album seeing as I am somewhat fond of her, but still, her with the 'Babes is amazing enough for me.
