As we've seen before, the Jenner sisters don't have the best relationship with Selena Gomez. But if this rumor is true, things must be worse than we thought! According to a recent report, Kendall and Kylie Jenner were overheard bashing the "Come and Get It" singer at the MuchMusic Video Awards last month.

The source overheard the Jenners calling Selena "fake" and saying that she doesn't care about anyone else.

"[If she got an award], she would probably accept it and then laugh at the people who voted for her," they allegedly said.

Selena dramatically ended her friendship with Kendall and Kylie earlier this year, supposedly because Kylie had a fling with Justin Bieber. Now that Jelena might be back on, people are speculating that's what is causing this renewed tension.

Of course, nothing has been confirmed or denied, and we're not entirely convinced that Kylie and Kendall would say bad things about Selena in such a public place!

Do you believe that Kendall and Kylie were gossiping about Selena? Sound off in the comments.
