The controversial public speaker spared no punches during her latest verbal attack, berating TOWIE star Lauren for using the pool as a toilet.

Lauren was called to The Diary Room, where she was told off for urinating in the pool, and told it was 'immature behaviour for a 27-year-old'.

And Katie, 39, didn't miss the chance to play Big Brother's teaching assistant.

"Lauren, please don't confuse the pool with the toilet again. And you can take those marshmallows off from round your mouth as well #CBB," the mother-of-three sniped.

And former Apprentice contestant Katie isn't the only one who isn't a fan of her lips.

Lauren's mother Cheryl recently admitted she didn't approve of her daughter's cosmetic procedures, adding:

'[Lauren] was so pretty. I don't like the big lips. I wish she'd stop.

'I'm not against her having her nose done though.

'But she really didn't need a boob job.’

However Lauren's mum admits some of her insecurities may stem from her childhood, explaining:

"[Lauren's insecurities stem from] when she went to live with her dad at four.

'I was very depressed after I had Lauren. I didn't get any help and I sort of rejected Lauren because of that.'
