Lady Gaga puffs a cigarette outside her trailer on House Of Gucci set

She has been gracing the House Of Gucci set in a series of jaw-dropping ensembles, amid a perfect impression of Patrizia Reggiani.

Yet Lady Gaga proved Rome wasn’t built in a day as she was spotted behind-the-scenes on the Italian set of the upcoming movie, while rocking a hairnet and smoking a cigarette outside her trailer. 

The songstress, 35, real name Stefani Germanotta, was worlds away from the part she plays as she arrived on-set in scanty, knitted three-piece – complete with a bralet, high-waisted shorts and a matching cardigan.

Gaga looked like she had some time to go before transforming into the fashionista as she was seen with her hair tightly packed beneath the net. 

She was clearly having some downtime between scenes as she could not resist slipping in a cigarette before turning herself to full transformation.  

The story Gaga and her on-screen husband Adam Driver are playing out is that of Reggiani, who was found guilty of paying a hit man €300,000 (£240,000) to murder her husband – 46–year–old Maurizio Gucci, an heir to the fashion empire.

Her husband had left her for another woman 10 years previously after telling her he was going on a short business trip, from which he never returned.

She was also said to be furious her former husband had started seeing other women, and feared her daughters’ $170million inheritance was at risk if he remarried before ordering the hit.

She also wanted more than the $650,000 she had been offered in a divorce settlement, the court heard.+

Reggiani eventually hired hitman Benedetto Ceraulo, a debt-ridden pizzeria owner who shot Gucci dead on the steps of his office in Milan as he arrived for work. Ceraulo was convicted and sentenced to life in prison.

She was convicted after her clairvoyant and confidante Pina Auriemma turned informer and told police about the plot.

During the murder trial, which transfixed Italy, Reggiani arrived each day wearing head-to-toe Gucci clothes and accessories. The court heard how she had ordered the murder of her husband after he offered her $650,000 in a divorce settlement.

She was initially sentenced to 29 years in 1998, which was reduced to 26 on appeal. She served 18 – with her pet ferret Bambi as a companion for some of the time – before being released in October 2014.

Having Bambi by her side was a special privilege negotiated by her lawyers — however he was to suffer an unfortunate demise when a fellow inmate accidentally sat on him.

Well-known for her luxury lifestyle, Reggiani once said: ‘I’d rather cry in a Rolls than be happy on a bicycle’ and turned down the offer of day release while in prison because it would have meant doing ‘menial’ work.

In 2017 a court ruled Reggiani was entitled to receive £900,000 a year from her ex-husband’s fortune and she was given a lump sum of £16million for her time in prison.

Maurizio Gucci was the grandson of Guccio Gucci, founder of the fashion company made famous with its double G logo. In the early 1990s it was hit by problems and he sold the label for $120 million, just two years before his death.

The Gucci empire 

The fashion empire of Gucci was founded in 1921 by Guccio Gucci, a Florentine leather merchant whose business of selling leather travel bags prospered after the Depression and World War Two.

Guccio’s son Aldo expanded the business into Paris, New York and Tokyo as the ‘twin Gs’ of the family name became a worldwide fashion icon.

By 1974, the Gucci empire numbered 14 stores and 46 franchised boutiques around the world.

At around the same time, celebrities like Jackie Kennedy were helping establish Gucci as the world’s leading fashion brand by embracing its products.

Maurizio Gucci, Guccio’s grandson and Aldo’s nephew, took control of the company from the board of directors after Aldo, who was sent to prison for tax evasion in 1986 aged 81.

However, Maurizio would be the last member of the family to head the Gucci business.

By 1989, nearly 50 per cent of the business had been bought out by Investcorp, a group of investment bankers angling for shares of the business.

In 1993, Maurizio sold his holding for $170m to a Bahrain-based investment company.
