Robert Pattinson’s fiancee FKA twigs celebrated her birthday with the actor in London on Saturday. Twigs, who turned 28 on Jan. 16, was spotted partying in central London with the “Twilight” star on Saturday.

According to Mail Online, Pattinson and his pop star fiancée partied at a famous celebrity hangout at Soho’s The Box. The duo kept a low profile as they arrived at the venue together in a chauffeur driven vehicle. Check out their pictures here.

On her birthday, the pop star wore a long black dress, which she paired with black ankle-length shoes. Keeping the London weather in mind, the “Glass & Patron” singer wore a classic grey-coloured designer long coat. She kept her make-up minimal and let her natural curly hair flow in style over her shoulders.

Meanwhile, Pattinson was seen sitting by her side in a taxi as they returned home. The actor wore a thick dull green jacket, black pants and a black baseball cap. The duo partied till the early hours of Sunday, added the website.

Twigs, who was born Tahliah Barnett in rural Gloucestershire, England, has faced a lot of criticism from Pattinson’s fans ever since she started dating him. She was trolled on Twitter and also called a “monkey-face.” Pattinson’s fans compared her to the actor’s ex-girlfriend and “Twilight” co-star Kristen Stewart and were not happy with the fact that she replaced Stewart.

The British pop singer opened-up about the online criticism in her previous interview with The New York Times. “There’s no amount of songs I can sing or dances I can dance that will prove to them [Twitter trolls] I’m not a monkey,” she said.

However, the songstress also admitted that her relationship with Pattinson is worth all the criticism. “I didn’t see my life going this way at all. But it’s worth it. I’m so happy,” she said at that time.
