Austin Armacost - the ex-boyfriend of fashion designer Marc Jacobs and star of US reality TV series 'The A List: New York' - has slammed the celebrity blogger and promised to be a "truth-teller" on the show.

Austin, 27, said: "He's an absolute k**b - ironic as he's famous for drawing k**bs on celebrities' foreheads.

"I can't believe no one lost their temper and walloped him. He is everything I despise.

"I am a truth-teller. If I know another housemate is being shady, sneaky or conniving, they will be confronted about it."

The new Channel 5 series will have a UK v USA theme and has already signed up American model Janice Dickinson and former 'The Only Way Is Essex' star Dan Osborne.

Austin - who is married to a British LGBT activist Jake Lees - is a frequent social media user and describes himself as "exuberant, eccentric, outgoing, loud and big mouthed".

An insider told The Sun newspaper: "Austin is a great signing and will bring loads of drama to the house. He is not afraid to say what he thinks and can be pretty catty."

'Celebrity Big Brother' kicks off at the end of August on Channel 5.
