The premiere of the highly anticipated movie, "House of Gucci" was held on Tuesday at Odeon Luxe Leicester Square in London. The star-studded movie’s cast members attended the event including Lady Gaga and Adam Driver who were spotted hugging on the red carpet.

A Twitter user shared a video from the event on Tuesday, where Gaga is seen wearing a beautiful purple outfit while Driver donned a formal black suit. In the video, Gaga rubbed Driver's back as they hugged each other and then posed for a photo together.

In a photo shared by another user, both the actors could be seen posing together for the camera. In the photo, the "A Star Is Born" actress flaunted her left leg's stocking by lifting her dress up and her co-star couldn't help but stare at her leg.

The official Twitter handle for the movie shared a video of the red carpet event featuring all the cast members including Jared Leto, Salma Hayek, Jeremy Irons, Camille Cottin and Madalina Ghenea.

"Hottest. Red Carpet. Ever," they wrote in the caption.

They also shared a series of photos captured on the red carpet and captioned them, "Cementing this as the pinnacle of high fashion red carpet moments."

While Gaga donned a purple outfit, Hayek wore a golden, glittered gown. She completed her look with a beautiful matching necklace and a bracelet. During the event, Gaga and Hayek also shared a hug and a brief conversation that was captured in photos.

Leto, on the other hand, wore a blue velvet suit over a bare torso and a silver chain around his neck. He completed his look with white shoes.

"House of Gucci" is based on the true events of Italian socialite Patrizia Reggiani's life who was convicted of ordering her ex-husband's assassination. Driver played Maurizio Gucci in the crime drama flick while Gaga portrayed Reggiani's character in the movie.

The movie is directed by Ridley Scott and slated to release on Nov. 24 in theaters.

Apart from this crime drama, Gaga is currently filming her own untitled documentary helmed by director Terry Richardson. Driver, on the other hand, will be seen in upcoming movies "65" and "White Noise."
