Gomez took to Twitter to criticise celebrities airing their trivial disagreements on social media.
"Why can't people use their voice for something that ... matters?," she said, adding that last thing that was needed right now was "hate, in any form."
Gomez, who is friends with Swift, was apparently referring to Kim Kardashian, who leaked a video of her husband West discussing with Swift the lyrics to his controversial song 'Famous'.
Swift has previously blasted the rapper for the lyrics but both West and Kim maintained that she had approved the lyrics before they became public.
"Everyone in this industry needs to get their heads out a hole and look around to realize what's ACTUALLY happening in the REAL world," Moretz tweeted.
She said people should stop wasting their time on something so "petulant and unimportant.
