Teenage actress Chloe Grace Moretz has gone on the attack after tiring of Internet trolls who poke fun at her and boyfriend Brooklyn Beckham.

The 19-year-old Kick-Ass star recently went public with her romance after trying to keep her relationship with Victoria and David Beckham's son under wraps for months, and the news really turned the young couple into targets on social media.

And Moretz is really getting sick of "people hiding behind computer screens", taking to Twitter on Tuesday (28Jun16) to ask when they'll get "tired of calling someone 'fat' or 'masculine'?"

"Does it make you feel good typing your hateful comments?" she asks. "Does it fulfill you in some dark way?"

It's not clear exactly what prompted the teen's rant, but she reminded detractors that people who write ignorant things on a celebrity's profile are hurting a "real HUMAN BEING".

"He or she is a PERSON, with feelings and thoughts and a life that you are affecting so negatively," Moretz added.

"I've spent my whole life in front of cameras growing up with miscellaneous people judging and critiquing every little thing about myself. It's time we all stop hiding behind keyboards pretending we know even the smallest thing about the people we judge."

She ended her note by stating: "That's all - have a nice taco Tuesday guys."

It's not the first time Moretz has taken to Twitter to rant about serious issues - she found herself in the middle of a feud with Kim Kardashian after targeting the reality TV star for posting a nude selfie of herself on social media, writing: "We have so much more to offer than just our bodies."
