Lady Gaga embodies Harley Quinn in glamorous outfits ahead of Joker 2 launch

Lady Gaga looked the picture of on-trend style as she posed for pictures alongside her co-star Joaquin Phoenix for the London photocall of her latest film, Joker: Folie à Deux.

The 38 year old singer turned actress swapped her usual blonde tresses for a short cropped red hair style and complimented her new hair colour with a black and white patterned playsuit.

She completed her look with a pair of white stockings and six-inch black platform shoes. Ooozing style, Lady Gaga held an air of mystery to her appearance as she opted to wear a pair of black sunglasses.

Meanwhile, Joaquin donned a more casual appearance in a black hoodie, matching trousers and a pair of black and white trainers.

The stars of the film were on the roof top of London's Corinthia Hotel. Earlier this week the globally renowned singer attended the premiere of her latest film and sent the crowds wild.

Dressed in a floor length red gown, Gaga completed her look with a red bob. But it looks as though she is making the most of her time in London, if recent pictures are anything to go by.

The stars were also at the Venice Film Festival to promote the sequel to the box office hit Joker. Lady Gaga plays the role of Harley Quinn in the upcoming thriller.
