Dame Vivienne Westwood is shut in a 10ft high birdcage to protest Julian Assange's extradition to the US.
The large cage has been set up outside the Old Bailey for maximum impact.
Sensationally the world-famous fashion designer, 79, claimed the infamous prisoner has been "set up" by the CIA during a Good Morning Britain interview on Thursday.
Live on air, the fashion guru slammed Good Morning Britain's portrayal of Assange ahead of her staged protest.
She told Good Morning Britain: "Well first of all I want to say your introduction is exactly the total misrepresentation of Julian Assange that's going on for all that time.
"None of any of this is true. He's been trapped. It's been a collusion of all the governments involved America, Britain and Sweden.
Assange is incarcerated in HM Prison Belmarsh on remand since September 22 last year after an extradition warrant was issued in the US.
The US have demanded Assange is handed over to face trial for 17 charges under the Espionage Act for releasing classified documents about US foreign policy and the Iraq and Afghanistan wars.
His friend and global fashion icon Vivienne had no qualms climbing into a 10ft high bird cage suspended outside the Old Bailey in protest of his extradition.
Onlookers watched as the star was seen monkeying around on the bars and squawking.
Vivienne claimed Assange had been "set up" by the CIA and now was "completely trapped".
She went on: "And from the very beginning, starting with a honey trap, he's been completely trapped.
"It's a set up organised by the CIA."
Good Morning Britain airs weekdays at 6am on ITV.
