The Bad Thing singer said she is "rooting" for her former bandmates and wishes them all success.
'As long as you're not hurting anybody or speaking negative about anybody's race or culture, you should be able to enjoy your body however you want to.'
The singer said it was not being famous that made her unhappy but the pressure of working in a girl group.
The former S Club 7 star said she feels empathy for Jesy Nelson, after she was repeatedly targeted by vile trolls.
The former Little Mix singer has complained all the filters on Instagram shrink her nose, questioning 'What's wrong with a standard nose?'.
The girlband won the TV talent show in 2011 but say it has dropped in ratings for being too scripted.
The singer said 'nerves had got the better of her' during the group's performance.
