While discussing Jemma on the spin-off show hosted by Rylan Clark-Neal, Katie refused to criticise the new housemate.
Instead she chose to say: 'I'm a professional. That's why I've come so far in this industry. It doesn't matter who says anything about me.
'I [could] air it to you lot, but I will keep it in because I'm more respectful.'
Although she did add: 'But what I will say is, there's a lot of big characters in there and I think she won't even shine.'

'She'll be out quick,' Katie predicted. 'There's so many personalities in there, she's not shining already... it's early days, but good luck to her.'
Taking aim at Jemma once more on the show, Katie had claimed the buxom brunette is 'worth nothing' when host Rylan revealed that this year there is £50,000 up for grabs to go to a celebrity's chosen charity.
