Twilight heartthrob Robert Pattinson and FKA twigs have reportedly postponed their wedding plans.

According to a report in People, the pair have pushed back their nuptials until the autumn.

The 27-year-old singer, whose real name is Tahliah Debrett Barnett, "can't decide what [kind of] wedding she'd like to have."

It was previously reported that the 29-year-old Remember Me actor and twigs are planning to tie the knot in a low-key ceremony in London this summer.

"She talks about it keeping as real and low-key and then wants an elaborate glamorous Baroque affair," a source said. "She was even talking at one stage about having a masked ball."

"It will now be bigger but how big, nobody's quite sure at this moment in time," the insider added. "There's no fixed [wedding] date but will probably be late in the year."

In 2012, Pattinson ended his relationship with American actress Kristen Stewart, his Twilight co-star and girlfriend of four years, after it was confirmed that she cheated on him with British director Rupert Sanders.

Stewart and Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Pattinson and twigs are very open about their relationship.

At the Mercury Music Prize Awards, twigs was asked how her relationship with Pattinson was going, to which she replied: "Very good, thanks."

During an interview with The Guardian's magazine, The Observer, she went even further and called Pattinson "the man that I love."
