Robert Pattinson's relationship with FKA Twigs has been scrutinized and debated on ever since it was confirmed that the two were dating. Now, a report states that the couple is on the verge of cancelling their engagement and breaking up due to Twigs "hunger for fame."

Anyone getting into a relationship with Robert Pattinson is guaranteed to be placed under intense scrutiny and discussion. And that has never been more evident than when the "Twilight" star got engaged to British singer Tahliah Debrett Barnett, who's more well-known by her moniker FKA Twigs.

The two have been battling breakup rumors ever since they first got together and now that they're engaged, the rumor mill has been working overtime.

Reports have surfaced that the couple is on the verge of calling off their engagement because of FKA Twigs "hunger for fame." According to the gossip site "Celeb Dirty Laundry," the 29-year-old actor is questioning his engagement to Twigs due to her changing attitude.

The site reported that the dancer's changing attitude towards their wedding was one reason why it was delayed. Pattinson reportedly noticed that Twigs' initial plan to have a small, intimate wedding was slowly turning into a big spectacle. The dancer is also said to have been pushing her fiancé to take on more mainstream roles so he can remain in the spotlight.

But these rumors have been debunked by the Gossip Cop site, which reported that there's "no truth" to the rumors that the erstwhile Cedric Diggory is considering calling off his engagement.

However, there have also been reports that the couple's very busy - and different - lifestyles were the main reason why they haven't set a date for their wedding yet.

In a previous interview, the 27-year-old trip hop singer revealed that she's traditional and prefers the country life when she settles down, which is something Pattinson is said to be wary of.

The actor is also busy filming the movie, "The Lost City of Z," with Charlie Hunnam and Sienna Miller.
