AMERICAN TV has finally reached the bottom – after model Tyra Banks broadcast the first live colonic irrigation.

The procedure was carried out on a mother-of-two on Tyra’s chat show on Friday afternoon.

When the programme opened, an excited Tyra told her stunned audience: “It’s never been done before on live TV and we’re doing it!”

A mother-of-two called Brenda agreed to be shown undergoing the popular detox procedure.

It was carried out by ‘colonic hydrotherapist’, Tracy Piper.

Tracy told Tyra she carries out the procedure on celebrities in the US - but declined to reveal any names.

Tyra, who revealed she has had the procedure in the past, said: “After I did it, I had to run to the toilet.”

But she added: “I don’t think I’ll ever have it again.”

Thankfully the contents of Brenda’s lower intestines were not shown on TV.

But Tracy said: “In the past, I’ve seen fruit stickers, mushrooms, chicken and even worms.”

As jaws dropped in the audience, she added: “With worms I usually send a photograph to the person’s doctor in case they need treatment.”
