Robert Pattinson and fiancée FKA Twigs, born Tahliah Debrett Barnett, have reportedly called off their wedding. It's believed the long-distance relationship coupled with their busy schedules finally took its strain on their relationship that they have both ended their engagement.

A source specifically mentioned to Life & Style magazine (via HollywoodLife) that the breakup was caused by a major fight. The source claimed the argument started after FKA called Pattinson and told him that she couldn't visit him because of her busy schedule. Pattinson told her that he was not happy about it and FKA "lost her temper."

"[FKA] yelled at him to stop complaining and hung up on him," the source told Life & Style.

Pattinson and FKA have reportedly not seen each other since that alleged fight, which according to Hollywood Life happened on the first day of shooting for Pattinson's new film "The Lost City of Z" on Oct. 1. Since then the couple has decided to end their engagement.

The Life & Style source added that Pattinson's family are not really disappointed over the split and don't care if he and FKA are fighting. His parents reportedly think that FKA is not the right girl for Pattinson.

However, this is not the first time Pattinson and FKA have been hit with split rumors. Last month it was reported they have called off their engagement because they have different opinions when it comes to starting their own family.

A source told Heat magazine (via Sugar Scape) that the couple was no longer "on the same page" when it comes to their future. The "Twilight" star reportedly "wants to get married and have kids. " However, FKA has other things on her mind aside from being the mother of Pattinson's babies.

"Tahliah [FKA Twigs] isn't in any rush. She wants to one day, but not now -- they fight about that, as Rob pushes her. But she's too focused on her music career. Then Tahliah told Rob she couldn't keep planning the wedding if they aren't in agreement about the future," the source said.

The source added that their busy schedules were another factor in their breakup. Plus Pattinson and FKA were reportedly "finding it hard to talk because of the time difference."

However, an anonymous insider told Gossip Cop that there is no truth to the recent split rumors. Pattinson and FKA have not called off their engagement. The source likewise said the alleged phone call and fight never even happened.
