Rihanna leaves nightclub in black dress and oversized bomber jacket after partying until 4.45am

The singer and actress has been promoting her newest film in London, and was seen partying into the early hours of the morning at England's Scotch Nightclub.

The Umbrella singer was wearing a sleek black dress, and had covered up with an oversized bomber jacket with a hood that she used to cover her head. She also tried to hide her face behind a large pair of sunnies at 4:45am.

She completed the look with a pair of strappy black open-toed heels. Rihanna added just a dash of color to the look with a pink lipstick, and the orange lining of her jacket.

Carrying a black handbag embellished with hearts, she wore a choker necklace and an anklet, along with a loarge cocktail ring.

During her trip to London, the singer and actress was also present at Cineworld Leicester Square in London for the European premiere of her latest film Ocean’s 8.

For the event, Rihanna opted for a gold metallic dress that had an off-the-shoulder design, showcasing the singer’s tattoos. By far, the most interesting aspect of her outfit was the décolletage that showed off her cleavage.

She chose a couple of big shiny rings, as well as a pair of golden earrings that were the perfect complement to her outfit. For her makeup, the singer opted for a thick black mascara and a bright red lipstick.

Unfortunately for her, the dress’ design proved to be a risky one as she suffered a slight wardrobe malfunction at the event. One of the loose sleeves of the dress dropped so low that it almost flashed Rihanna’s breast.

That incident - which was not the only one during the course of the evening - took place while the star was walking to London’s Laylow restaurant for the after party.

Others who had attended the celebration were among her costars for Ocean's 8, including Sarah Paulson, Sandra Bullock, Mindy Kaling, and Cate Blanchett.

Ocean’s 8 addressed the story of Debbie Ocean, portrayed by Bullock, and her attempt to rob a $150 million heist at the Met Gala.

She recruits the other seven women played by Paulson, Kaling, Blanchett, Rihanna, Anne Hathaway, Helena Bonham Carter, and Awkwafina to carry out the plan.
