Selena Gomez disses Justin Bieber on Instagram? Unfollows (ex) boyfriend and BFFs Taylor Swift, Kendall & Kylie Jenner, 'emotional cleanse' after rehab?

Apparently, Selena Gomez is going through some major life changes - hopefully for the better!

Several gossip reports confirm that the "Come & Get It" songstress recently unfollowed her infamous on-and-off again boyfrind Justin Bieber on Instagram. In today's world of social media, that's a rather big diss!

And yes, Gomez was indeed following the Biebs on Instagram up until a few days ago.

But that's not all - the former Disney sweetheart also "dumped" rumored BFF Taylor Swift, and close gal pals Kendall and Kylie Jenner! So what's up with that?

Gomez and the stunning "Red" songstress both unfollowed eachother on Monday (April 21). That same day, the 21-year-old "Love You Like a Love Song" beauty posted these emotional Mary J. Blige lyrics on the popular photo networking site:

Pretty intense. Following her stint in rehab, Gomez appears to be "cutting ties" with some negative influences in her life - does that include the Biebs?

Hollywood Life reports that on Monday, Gomez cut her list of "people I'm following" down to just 15. That number is now back up to 59.
