Robert Pattinson and FKA Twigs' upcoming wedding is allegedly in peril as the couple has hit a rough patch in their relationship.

People ran an article that claimed the "Twilight" actor and the English Indie singer "have drifted apart" and the wedding right now is "off the agenda."

One good news, however, is that Robert Pattinson and FKA Twigs have not called off the engagement yet, which means the wedding may still on the table.

The article claimed that the distance only further drove a wedge between the couple.

FKA Twigs is currently in Los Angeles, California while Robert Pattinson is filming in Ireland for "The Lost City of Z."

"Lost City of Z," according to the summary, "follows Percy Fawcett, a conscripted soldier and born explorer who disappeared in the 1920s while searching for a mythical city in the Amazon jungles of Brazil that he believed he discovered on a prior expedition."

"They've definitely drifted and have barely spoken while he's in Belfast and she's been in the States," the insider told People.

One of the problems was that,"Rob has never been at ease with twigs' entourage."

The couple was said to have been engaged during the Coachella Music Festival earlier this year.

Previously, Celebrity Dirty Laundry claimed that the wedding plans have caused some arguments between the couple especially since FKA Twigs wants a high-profile ceremony.

"Rumors suggest Pattinson and Twigs argue over wedding plans as the singer now wants a big, glamorous ceremony, while R-Patz pushes for a low-key event," the article reported.

It added, "Robert has always been on the shy side when it comes his personality. Embracing the angsty hipster style, Pattinson prefers to be more reserved and rarely indulges in flashy nuances. Perhaps that is why he was originally drawn to FKA Twigs?"

Robert Pattinson and FKA Twigs have yet to respond to the rumor that their wedding might not push through.
