The Kardashians were definitely NOT on their best behavior at the VMAs on Aug. 24! Not only did they appear to be texting during the Ferguson memorial, but they also left right before Beyonce’s emotional acceptance speech, a source tells HollywoodLife.com EXCLUSIVELY. Major diss!

It looks like Kim Kardashian, 33, may still be holding a grudge against Beyonce, 32, for skipping her and Kanye West‘s wedding in Florence, Italy on May 24! Kim and sisters Kylie Jenner, 17, and Kendall Jenner, 18, apparently were not loving Queen Bey’s amazing performance at the MTV Video Music Awards, because they had the nerve to leave when she was finished with her epic medley, a source tells HollywoodLife.com EXCLUSIVELY. So shocking!

Kim Kardashian On Beyonce’s Performance At VMAs: Kim & Sisters Leave Before Speech

Sorry, Beyonce — Kim, Kylie and Kendall are just not that into you.

An eyewitness source who attended the VMAs tells HollywoodLife.com EXCLUSIVELY, “I saw them leave before Beyonce’s started her speech. They were checked out for the whole show. They left right before she talked and Jay Z arrived to give her the award.”

We know Bey’s performance ran a little long, but you’d think they could have waited it out for her to accept her award! Do you think the Kardashian sisters could have skipped Bey’s special moment on purpose?!

Beyonce Gives Sexy Strip Tease For Jay Z During 15-Song Medley At VMAs

To be fair, Queen Bey did perform her entire new album — fifteen songs — when she took the stage at the VMAs! There were some sweet moments — she teared up when she sang to daughter Blue Ivy during her performance of “Blue” — and some sexy moments –she was grinding and dancing on a stripper poll for Jay Z at one point!

Beyonce wrapped things up by dedicating “XO” to her millions of fans — which apparently does not include Kim, Kylie and Kendall!

So what do YOU think, HollywoodLifers? Was it rude of the Kardashian sisers to leave in the middle of Beyonce’s VMAs performance? Let us know!
