Jared Leto has completely transformed for his part in the upcoming movie "House of Gucci."

The Oscar-winning actor/musician, 49, plays Paolo Gucci, the former vice president and managing director of Gucci, in the film directed by Ridley Scott.

The movie tells the tragic but true story of Patrizia Reggiani, played by Lady Gaga, who served 16 years in prison for plotting the murder of her husband Maurizio Gucci, portrayed by Adam Driver.

Leto shocked fans with his look for the film. He donned prosthetics for the role in a poster released by the film on Thursday.
