The singer's accessories were equally as bold, as she wrote fishnet stockings, a pair of sheer, sparkly black gloves and black sky-high platform booties.
"Most people would be very excited to play a chancy, risky, gold-digging murderer who gets off on chaos and f**king up people’s lives.

The Oscar winner mesmerized in a turquoise velvet suit, diamond jewels and white shoes.
In the flick, he play Paolo Gucci, who's much heavier and bald. "It's just what I'm interested in," he explained to Entertainment Weekly of transforming physically for his roles. "When you make that kind of commitment, there's something that happens. You're compelled to dig even deeper, to work even harder, to discover something more rewarding and richer."

Lady Gaga & Adam Driver
The pair, who play spouses-turned-exes in the movie, showed off their playful chemistry on the red carpet.
The Ridley Scott-directed flick is based on Sarah Gay Forden's 2001 book, House of Gucci: A Sensational Story of Murder, Madness, Glamour, and Greed. Both stories recount how Patrizia Reggiani (Gaga) was tried and convicted in the orchestrated murder of her ex-husband Maurizio Gucci (Driver), who was also head of the iconic fashion brand.
