Robert Pattinson And FKA Twigs Engaged In Big Fight; Singer Jealous For Actor's Ex, Kristen Stewart

Robert Pattinson and FKA Twigs have a big fight over Kristen Stewart .

The celebrity couple may have a hard time recently as the Two Weeks singer is still 'jealous and 'insecure' with Rob's ex onscreen and off-screen sweetheart in such a way that she does not want the two to get close to each other even in gatherings related to showbiz.

Hollywood Life said that that Twigs 'screamed' and 'went ballistic' when her fiancée suggested to support Kristen in the premiere of her recent film, Clouds of Sils Maria at NYC.

The insecurity and jealousy of the singer is said to have made matters worse as Rob is now starting to have doubts in their relationship.

"Now, as his relationship with Twigs gets more volatile, he's feeling completely torn between the two women," the source said.

It can be remembered that Rob and Twigs have postponed their wedding despite being engaged for months. Earlier sources said that the couple have been filled with indecision particularly the singer who has trouble deciding whether to have a low-key or an elaborate, grand wedding celebration.

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

 However, a recent report from Movie News Guide said that their conflicting schedules, and not the lack of approval from Twigs' parents or Twigs indecision, is the main reason why they delayed their marriage.

And, despite rumors, the publication said that Robert Pattinson and FKA Twigs are happily spending time during the holidays, holding hands while strolling the streets of London before New Year's Eve.
