Tinsel Town is buzzing with stars dissing each other on various platforms. The most popular one is dissing on Instagram. From Selena Gomez to Rihanna to Justin Bieber, celebs are on a dissing spree for various reasons like breakups, linkups, ego trips and more. Check out the most shocking Instagram disses in recent times.

Rihanna Vs. Chris Brown

Rihanna and ex-boyfriend Chris Brown have not been buddies. A source close to Rihanna told HollywoodLife.com that she has been dissing Chris big time after he was put behind bars.

The source informed that Rihanna feels that Chris "abuses his fame."

"There are millions of people out there who would take opportunities that he has been given and would be so humble and grateful and would never squander their luck."

The source added that the "Rude Boy" singer hopes that one day Chris will find himself and be a good man.

Selena Gomez Vs. Kylie and Kendall Jenner, Austin Mahone, Justin Bieber - Toxic Folks

Reportedly, Selena Gomez is done with "toxic people" in her life. Reports suggest that the "Come & Get It" singer unfollowed Kylie and Kendall Jenner from her Instagram account after having a great time with the sisters at Coachella 2014.

According to TMZ, the Jenner sisters are nothing but a toxic distraction for Selena and she is happy without them.

Sources told TMZ that Selena realised this after Coachella last week where she was with Justin Bieber, Jenner sisters, alcohol and drugs.

Now, Selena is sick of all these things and ready to cut the ties for good. She now follows no one on Instagram including Justin Bieber, Jenner sisters and Austin Mahone.

Talking about Austin Mahone, HollywoodLife.com reported that after Selena unfollowed him on Instagram he was incredibly sad and even shed one tear.

Even Justin Bieber dissed Selena Gomez big time after he made things public about them getting busy at Palm Springs. Reports suggest that Selena agreed to have sex with Justin as they said they were in love. However, Justin made it public and a special trip became one of the rudest things done by the "Baby" star.

Who do you think is the rudest of them all?
