The 28-year-old star's fitness DVD has also outsold former Big Brother host Davina McCall's fitness DVD.
However the 5”10 reality star admits that she prefers being a size 10-12.
Referring to TOWIE star Gemma Collins’ recent comments accusing Josie of having lost too much weight and ‘having lost her lovely face', Josie said:
‘I love Gemma - she's so funny.
'I don't think she meant to call me ugly but I know what she means.
'My mum said the same thing.
'When I went down to a size 8, my mum said: ‘You look like a crackhead - put some weight on!'

'It's hard to find that happy balance but I have put some more weight back on - 7lb.
'You have to compromise with your face and your body sometimes.
'There's a balance.'
We love your healthy approach Josie!
