The wedding between Robert Pattinson and FKA Twigs might not push through if the rumors claiming that the "Twilight" actor's sisters do not approve of the relationship are true.

According to Celebrity Dirty Laundry, "overprotective" sisters, Lizzie and Victoria, have been nagging Robert Pattinson against pushing through with the wedding.

"Robert Pattinson desperately wants his family's approval and blessing before he walks down the aisle and marries FKA Twigs, but sources say his sisters Lizzy and Victoria are not on board with the rushed wedding," the article claimed.

Robert Pattinson's sisters also have been demanding that he signs a prenup if he wants a wedding to FKA Twigs in order to protect his millions. Apparently, the article claimed, the British indie singer is a "gold digger" who will "take him for every penny he is worth."

The singer has been accused of using Robert Pattinson to further her career.

In an interview with Complex magazine, FKA Twigs revealed that she was bullied and harassed by some of Robert Pattinson's fans, and some of the attacks had racial undertones.

"It is pretty horrible. But ultimately, I'm in an amazing relationship. So it doesn't matter," she added.

FKA Twigs and Robert Pattinson were rumored to be rushing their wedding after they allegedly got engaged during the Coachella 2015. Aside from the the harassments, the British singer was also rumored to be pregnant.

In another interview with The New York Times, FKA Twigs admitted that it's quite difficult to date somebody when the paparazzi are hounding all their moves.

"[It's really hard - I can't begin to explain how awful it is. It makes you want to just stop everything sometimes. It makes you want to smash your face into the mirror," she said.

But all that comes with the territory in dating Robert Pattinson as FKA Twigs said, "I didn't see my life going this way at all. But it's worth it. I'm so happy...Nothing can impale my work or make me choose not to say things a certain way or make an image the way I want."
