Robert Pattinson's fiancé Tahliah Barnett aka FKA Twigs flaunted her engagement ring while at the Met Gala. An insider has revealed the cost of the ring that the "Two Weeks" singer recently received when her movie star boyfriend asked for her hand in marriage.

"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 MASbisjoux jewelry told E!Online about FKA Twigs' engagement ring worn during the Met Gala.

"It's quite the unique setting for quite the unique lady."

Prior to their Met Gala appearance, Robert Pattinson gave Tahliah Barnett aka FKA Twigs an engagement ring after dating for just less than a year.

E!Online added that their wedding plans are "moving very, very fast."

The engagement of Robert Pattinson to his girlfriend Tahliah Barnett aka FKA Twigs came amid criticisms from their online haters.

According to a report from Gigwise, the eccentric singer sat down for an interview with Zane Lowe on BBC Radio One and opened up about her bashers.

"I didn't want them to see me being bullied and not stand up for myself. Ultimately I'm 10 times stronger than somebody hiding behind a weird name on Twitter," FKA Twigs said.

"I wanted to show that I can stand up for myself so then hopefully another person will see that and want to stand up for themselves."

The English singer-songwriter admitted that she has read some of the things being written about her.

"I remember at the height when things were really bad for me. I remember lying in bed at three o'clock in the morning and it's embarrassing but I was just reading through everything, reading every single comment. I just couldn't believe the world was like that," she said.

According to a previous report from USA Today, Robert Pattinson's fiancé said she wants to focus on their relationship and not mind her haters.

"The positivity that I get from (my relationship) makes the more challenging aspects...very worth it," she said.
