Newly-engaged Robert Pattinson will not ask his fiancé FKA twigs to sign a pre-nuptial agreement because it is not romantic, reports said Thursday, citing sources. The "Twilight" actor, who is worth $60 million, had proposed to Twigs earlier this year with a $150,000 engagement ring after dating her for six months.

"Rob's quite a traditionalist and is madly in love with her, so he doesn't think it's necessary. He's following his heart on this, rather than his head," a source close to Pattinson said, according to the Mirror, which cited the Star magazine.

The couple reportedly plans to tie the knot in September at a low-key and quirky wedding. According to reports, Twigs, whose real name is Tahliah Debrett Barnett, wants a registry office ceremony, pub lunch and party with their friends later.

"She wants a hippie-style ceremony at a friend's house in the English countryside,” a source told Life & Style magazine, according to the Mirror. "He'll do whatever she wants. He just wants to make her his wife."

The engagement ring that Twigs is flaunting these days has also created some buzz. “FKA twigs is sporting a highly stylized bow-shaped ring featuring a pear-shaped diamond of approximately 4 carats with an approximate value of $150,000,” Morgan Shara of MAS Bisjoux jewelry, had reportedly said earlier this month.
