Robert Pattinson & Kristen Stewart Breakup New Update 2015: 'The Rover' Actor Reportedly Upset FKA twigs Made Fun of Kristen Stewart's Rumored Relationship with Woman [Pic]

Robert Pattinson is reportedly upset at current girlfriend FKA twigs for mocking his ex Kristen Stewart.

The "Pendulum" singer took to her Instagram account on Jan. 21 to share a snapshot taken in Japan.

Ever since then, things have reportedly not been going so well between the British couple according to Celeb Dirty Laundry.

"Robert Pattinson thinks FKA Twigs' Instagram photo of her sitting on a chair with breasts ridicules Kristen Stewart," and her alleged romance with best friend Alicia Cargile.

The website added "The Rover" actor is now "furious" and somewhat hinting he has not moved on from his "Twilight" co-star for good.

Stewart has been romantically linked to Cargile lately. According to RadarOnline.com, they are so close they even got matching tattoos of arrows on their right arms.

"They are inseparable and mimic each other's everything," an insider claimed.

The female pair was actually caught on video together, when they arrived back to Los Angeles on Jan. 2 from their New Year's vacation in Hawaii.

The insider also suggested Stewart and Cargile, who were seen supposedly showing affection during their holiday, might be more than just friends.

"When Kristen and Alicia were in Hawaii for New Years, I am sure that they thought no one was going to see them," the insider said. "But they are not exactly nonchalant about their relationship anymore.

"She just doesn't care what people think anymore," the insider added. "Kristen is happy and she is just being herself. She doesn't need to worry about where her next role is going to come from nowadays because she has proven herself as an actress."
