Matthew McConaughey is famed for his bulging biceps and rippling six pack... but not any more.
The star has revealed his shocking weight loss on the set of his new film The Wolf Of Wall Street.
Matthew looks unrecognisable after shedding over two stone to play the role of a HIV patient in a different film.
He was pictured yesterday on set looking gaunt and a far cry from the muscly stripper he played in his most recent film Magic Mike.
In the upcoming Dallas Buyers Club, which is due to begin shooting next month, Matt plays Roy Woodruff, a man who contracts HIV and decides to smuggle the drugs needed for his treatment over the border into the US.
In order to get into shape for the role, he has been pounding the streets of New York.
Earlier this year, speaking to Larry King's Ora TV web series he admitted the strict diet has already taken a toll on his health: "I should not look healthy by the time I'm doing (filming) this.
"It's a bit of a spiritual cleanse, mental cleanse. (I'm) drinking a lot of tea. It takes a while for your body to understand that it has to feed off of itself and that you're not going to give it something else from the outside."
Matthew recently tied the knot with model Camila Alves, who is currently expecting the couple's third child.
