The Gucci family has previously expressed concern surrounding the new film, saying it is an intrusion into the private lives of the Gucci heirs, appealing to the film's director Sir Ridley Scott to respect their family legacy.
The trailer for the highly-anticipated House Of Gucci has given fans their first look at the cast in the film.
The biographical drama is based on the book The House of Gucci: A Sensational Story of Murder, Madness, Glamour, and Greed by Sara Gay Forde, and is directed by Sir Ridley Scott.
It follows the events surrounding the murder of fashion monolith Maurizio Gucci, played by Star Wars actor Adam Driver, while Lady Gaga portrays Patrizia Reggiani, his ex-wife, who was convicted of orchestrating the killing by a hitman in 1995.
In the trailer, which features the Blondie tune Heart Of Glass, we see Gaga and Driver's characters celebrate their wedding, before discussing the ins and outs of the fashion industry in their Italian accents.
Teeing up the film's plot, Gaga says: "Gucci needs new blood - it's time to take out the trash."
Also featuring in the almost-entirely Oscar-winning or nominated cast, is Jared Leto - who looks unrecognisable as Paolo Gucci.
The 30 Seconds To Mars singer is seemingly kitted out in a fat suit and heavy prosthetics for his role as the grandson of the Gucci founder, Guccio.
His unkempt hair and lilac corduroy suit was said to have offended a cousin of Maurizio, Patrizia Gucci, when she first saw it.
Jeremy Irons and Salma Hayek (who is married to the current CEO of Gucci owner Kering) also appear in the film, as do Al Pacino and Jack Huston.
As much as the film is expected to do well when it hits the big screen later this year, it has not come without controversy.

Patrizia Gucci said: "We are truly disappointed. I speak on behalf of the family.
"They are stealing the identity of a family to make a profit, to increase the income of the Hollywood system... our family has an identity, privacy. We can talk about everything. But there is a borderline that cannot be crossed."
The family, which has not been involved in the fashion house for many years, says it will watch the film before deciding on its next steps.
House Of Gucci is scheduled for release on 26 November in the UK.
