Robert Pattinson and FKA Twigs have been engaged for over a year and according to a source, the “Two Weeks” singer has already grown impatient. She reportedly gave the “Twilight” actor an ultimatum to marry her this year or she is calling their engagement off.

Last January 16, the couple were photographed together during Twig’s birthday. They seemed happy but it was noted that the singer wasn’t wearing her engagement ring. And thus, speculations about the supposed ultimatum becomes louder and bigger.

“Twigs has told Rob this year they have to get married. She’s fed up of waiting, and she wants something small, quiet and private, so it doesn’t need any elaborate plans,” the source explained to Hollywood Life.

The source added that Twigs would like to do the wedding in the summer. “It may even be a registry wedding, in front of a handful of friends and family in the UK,” the source said.

A recent report claimed that Robert Pattinson’s friendship with his ex and former “Twilight” costar Kristen Stewart might be the reason why the lovebirds have delayed their wedding. Twigs reportedly freaked out when the actor suggested that they show their support for Stewart at an NYC event for her movie “Clouds of Sils Maria.” The report claimed that the singer was incredibly “jealous” and even screamed “no f***king way!”

However, the Gossip Cop pointed out that the news about Twig’s ultimatum is fabricated. “… the webloid doesn’t mention where or when FKA Twigs warned Pattinson he needs to marry her this year. And it’s because this scenario never took place,” the website asserted.

The Gossip Cop also noted that the supposedly huge fight between Pattinson and Twigs over the actor’s friendship with Stewart was not true. “That never happend, and FKA Twigs has not given Pattinson an ‘ultimatum,'” the website further stated.
