Robert Pattinson and his fiancee FKA twigs, who are a very private couple, might have just had their first public argument, according to various reports. There is speculation in the media that thy both fought two times during their recent night outs in London.

According to the Mirror, the couple was “heard swearing at each other in the back of a taxi,” a day after they both were seen attending the MOBO awards in London, where twigs also won the award for Best Video for her song, “Pendulum.” The website quoted a source as saying that the couple was heard “arguing after a night out.” The website also has pictures of the media shy couple hiding their faces from the paparazzi, inside a taxi.

"Twigs flung the door open and they started screaming at each other,” the website said, citing a source from The Sun. The website further stated that the actor was “livid” and used a swearing word to address twigs, asking her why she was waiting at that place when she was aware about his whereabouts.

The couple also allegedly “had a row” at MOBO awards in London when someone asked them to think about doing a song together, given Pattinson's interest in music. "He said that he'd love to, but she shook her head and he stormed off. She was comforted by a female friends outside the toilets. It was tense," the website quoted the source as saying.

However, neither Pattinson not twigs' representatives have confirmed these rumours. The couple looked happy in each other company when they attended the award ceremony together in London. They both shared the same table, smiled and Pattinson was in a good mood as he agreed to get pictures clicked with the fans too.

The “Twilight” star is currently busy shooting “The Lost City of Z” but he took time off from his busy schedule to show his support to twigs. Meanwhile, the British songstress was also spotted wearing her engagement ring.
