Selena Gomez Unfollows Kylie and Kendall Jenner on Instagram in an Effort to ...

First, Selena Gomez unfollowed Kendall and Kylie Jenner on Instagram. Now, she's cutting ties with them in real life.

Sources tell TMZ the realization came after the former Disney Channel star-who recently completed a stint in rehab, claiming stress-related issues were to blame-spent time with the reality starlets at the Coachella Music Festival April 12-13 and her on-again-off-again beau, Justin Bieber and realized they were 'nothing but a toxic distraction.'

Sel made her decision to eliminate the Jenners from her life public by unfollowing the two of them on Instagram-only to eventually purge all of her followers-and deleting the Coachella shots featuring the teenage sisters.

The source adds Selena is doing her best to stay straight.

As In Touch reports in this week's issue, on stands now, that might be the best course of action for the songstress.
