House of Gucci is released later this month.

Lady Gaga and Jared Leto are starring in a new movie about the murder of Maurizio Gucci by his ex-wife Patrizia Reggiani in 1995. House of Gucci is based on Sara Gay Forden's book, The House of Gucci: A Sensational Story of Murder, Madness, Glamour, and Greed. It follows the true story of how the head of the fashion house Gucci was murdered by his ex-wife and the trial that would later ensue. The film premiered in London, and on the red carpet last night were Lady Gaga, who plays Patrizia Reggiani and Jared Leto, who plays Maurizo Gucci. The cast features a star-studded lineup with Adam Driver, Salma Hayek, and Hollywood legend Al Pacino also appearing. This is Gaga's first performance since her Oscar-winning role in A Star is Born. She remained in character for 18 months while filming and has said that she feels connected to the character of Patrizia. "I would say that in terms of letting the character go, I don't know that I'd ever let her go." The premiere was as glamorous as the film's plot - Jared Leto is one of Gucci's brand ambassadors and was dressed head to toe in their designs in a fitted blue velvet suit. Lady Gaga and Salma Hayek followed suit with Gaga in a purple chiffon gown and Hayek in a pleated gold number. So far the film has received some mixed reviews. On one hand, it has been called "the most quotable/meme-able movie since Borat", and on the other hand, it has been referred to as a "crowdpleaser that critics will not support." The Gucci family in particular is not happy with this depiction of the story. "They are stealing the identity of a family to make a profit, to increase the income of the Hollywood system," they said. "Our family has an identity, privacy. We can talk about everything. but there is a borderline that cannot be crossed."  Patrizia Reggiani also came out to say she was "annoyed by the fact that Lady Gaga is portraying me in the new Ridley Scott film without even having the courtesy or the good sense to come and meet me."  You will be able to make up your mind about House of Gucci on November 26 when it's released in Ireland - and you can get a small taste with this trailer.
