It seems that the infamous love triangle feud is not quite over yet, as former girlfriends of Chris Brown, Rihanna and Karrueche Tran, are still fighting on social media.

Rihanna has made headlines recently for rekindling romance with Drake and is currently dating the Toronto rapper. However, she is clearly not able to either move on from the "Loyal" singer or let go of a grudge against her romance rival as she attempted to reignite the beef by insulting the L.A. model.

Karrueche Tran attended a charity event "HASHTAG LUNCHBAG" on Sunday and posted a simple photo of herself there via Instagram. The selfie features The Kill designer looking straight at the camera with a nametag placed on her chest on a bright, sunny day. "HELLO my name is," she wrote as the caption.

Shortly after, Rihanna also posted something on Instagram that obviously attacked Tran's previous snapshot. It was a mock doodle of an ugly face with a caption that read, "Say. My. Name."

The fight between the two has been going on for quite a while with the Barbadian singer constantly trying to put Tran down, while the model reacting to Rihanna's insults. In fact, they recently had a Twitter war after the "Pour It Up" singer's friends reposted a picture of Chris Brown's on-and-off girlfriend on Instagram and started making fun of her new hairstyle.

Rihanna quickly joined her friends on Twitter. "Bwaaahaaaaa!!!!! Yo I LOVE my friends ya cunt!!!" she tweeted. "My bitchez funny, but my niggaaaazzzz?????! LOL #messy."
