Kerry KatonaKerry Katona is a force to contend with.

It's no secret she's happy to speak her mind.

But her latest chat has even us reeling with its brutal honesty.

Talking to Heat magazine, Kerry kicked off by branding her estranged mum Susan "a sad, lonely, twisted woman" over her plans to sell a tell-all autobiography detailing shocking drug and sex allegations in relation to Kez's past.

Questioned about Susan's claims that she tried it on with her former hubby and father of two of her kids Brian McFadden, Kerry said:

"I'd be more surprised if she hadn't slept with him."

She then vowed "I won't slag Brian off" before adding:

"He should get his priorities right. F*** his career. He's supposed to phone the kids every other night at seven and he hasn't done so since March."

Ouch. Kerry, who suffers from bipolar disorder, also admitted she felt "suicidal" when she came off her medication while pregnant.

And to end off her candid rant, Kerry dismissed rumours of her present hubby Mark Croft cheating on her, saying:

"Mark isn't going to go our for burgers when he's got steak at home."

Right, gotcha, Kerry. Now, take a deep breath, love.
