Actor Robert Pattinson and his fiancée FKA twigs have postponed their wedding much to the dismay of fans.

A source claims that the couple's wedding plans have been delayed "until autumn at the earliest because the bride-to-be can't decide what [kind of] wedding she'd like to have," reports People magazine.

Twigs reportedly wanted a small, private wedding with close family and friends at a pub, but has since changed her mind.

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

Pattinson and FKA twigs, whose real name is Tahliah Debrett Barnett, have apparently ditched their idea of a pub wedding and now with more time will plan a more elaborate wedding and reception.

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

The wedding may be pushed back, but the celebrity couple has already revealed plans to have children.

Pattinson told German fashion magazine Jolie that he's "definitely" ready to be a father.

Twigs recently spoke about motherhood in an interview with Britain's The Sunday Times.

"Women are amazing creatures. We can give birth. We have a womb. We can create life! Are you kidding me? We can create life!" she said. "I honestly didn't give a sh*t about any of this stuff until about two years ago. I don't know whether it's my age -- I'm going to be 28 in January -- but all of a sudden I started thinking that if I had a daughter, it is gonna be terrifying."

The couple became engaged earlier this year following six months of dating.
