The 32-year-old singer-turned-actress pulled out all the stops at the premiere for the movie - which she stars in alongside Bradley Cooper - as she stepped out in an Elizabethan style gown designed by Alexander McQueen's Creative Director Sarah Burton, and paid "tribute to the actual runway show" by wearing her hair in a classy updo.

The show-stopping gown - which appeared on the runway in 2013 - featured a fitted halter-style bodice with intricate gold and pearl beading, cut-off balloon sleeves and an decadent lace ruff, similar to what Queen Elizabeth I was known for wearing.

Speaking to WWD, Gaga's longtime hairstylist, Frederic Aspiras said: "The dress is such an amazing masterpiece, so we had to do something that was complimentary to it and to show London a little bit of [Gaga's] style.

"I wanted to do something that was a modern Elizabethan-type hair, so I did my research on that era. Also, I wanted to pay tribute the actual runway show with the pin curls."

The film premiered on Thursday night (27.08.18) and the 'Just Dance' hitmaker was joined by former Oasis frontman Noel Gallagher, 51, and his wife Sara MacDonald, 46, co-star and film director, Bradley Cooper, 43 and Princess Diana's niece, Lady Kitty Spencer.

Frederic admitted he wanted Gaga's look to be "elegant and real" for the London premiere, but keep the "original and classic" Hollywood glamour we're accustomed too.

The celebrity stylist added: "At Haus of Gaga, we plan ahead and we test the look before. A lot of people can [re-create this look]. It's different than your normal chignon bun. It's a bit more elegant and regal.

"Everything has to be new, but still have a touch of the original and classic beauty of Hollywood. Here, it's about the movie - not being the character, just promoting the movie - whereas the music, it's about the feeling of the album, the songs. It's definitely different. It's also nice to change it up and not be conventional and still add a touch of Gaga into it. People have been very accepting of it."

Gaga and the fashion brand's founder Alexander McQueen had been close for year before the designer tragically passed away in 2010 after battling with depression, and Alexander even designed her notorious Armadillo boots that featured in her 2009 'Bad Romance' music video.
