Rachel Zoe is a ray of sunshine in a bright yellow caftan-style dress at star-studded House Of Gucci premiere

Rachel Zoe was a ray of sunshine at the star-studded Los Angeles premiere of House Of Gucci earlier this week.

The 50-year-old stylist to the stars posed up a storm on the black carpet at the newly opened Academy Museum Of Motion Pictures.

She brought back memories of the 1970s - the decade when the film begins - by draping herself in a canary yellow caftan-style frock.

Lady Gaga stars in the film as Patrizia Reggiani, who married Maurizio Gucci in the 1970s - and had him killed by a hit man in the 1995 a decade after their divorce.

Gaga herself cut a showstopping figure at Thursday night's Los Angeles event, standing for the photographers with Adam Driver who plays Maurizio.

Jared Leto and Al Pacino, who play other members of the Gucci family, were spotted at the screening as well along with their director Ridley Scott. 

Other celebs at the swank affair included Charli D'Amelio, Diplo, Vanessa Bryant, Salt-N-Pepa, Vivica A Fox and Ashley Tisdale.

Earlier this year Patrizia complained to the Italian wire service ANSA: 'I am rather annoyed at the fact that Lady Gaga is playing me in the new Ridley Scott film without having had the consideration and sensibility to come and meet me.' 

She insisted: 'It is not an economic question. I won't get a cent from the film. It is a question of good sense and respect.'

Gaga explained her decision in a new interview, telling British Vogue: 'You know, I only felt that I could truly do this story justice if I approached it with the eye of a curious woman who was interested in possessing a journalistic spirit so that I could read between the lines of what was happening in the film’s scenes.'

The Italian American celeb added: 'Meaning that nobody was going to tell me who Patrizia Gucci was. Not even Patrizia Gucci.'

'I was angry with Maurizio about many, many things at that time. But above all, this. Losing the family business. It was stupid. It was a failure,' said Patrizia in 2016.

'I was filled with rage, but there was nothing I could do,' she confessed before adding softly: 'He shouldn’t have done that to me.'

Although it was 1995 when she had a hit man dispatch Maurizio - the grandson of the brand's founder Guccio Gucci - she was not arrested until the beginning of 1997.

When a reporter asked her why she used an assassin instead of doing the job herself she joked: 'My eyesight is not so good. I didn't want to miss.'

The 'Black Widow's' trial became a media circus and she was convicted in 1998, serving 18 years before being paroled in 2016.

She had been offered parole a half-decade prior but turned it down because of the expectation that she would find employment.

'I’ve never worked in my life and I don’t intend to start now,' Patrizia reportedly informed her lawyer at the time.

The film is adapted from Sara Gay Forden's book The House Of Gucci: A Sensational Story Of Murder, Madness, Glamour And Greed.
