The 'Baby' hitmaker took this step less than one week after the 22-year-old pop star opened up about her relationship with Bieber in a revealing interview with Ryan Seacrest, reported E!Online.
Earlier this week, fans began noticing that Bieber no longer follows Gomez on the photo-sharing site.
Likewise, the brunette beauty does not follow her ex, and instead, limits her follow-backs to Gomez-centric fan sites.
