The One Direction singer, who is dating dancer Danielle Peazer, was outraged when users of the site tweeted derogatory comments about his girlfriend.
"Just as I start to like twitter again I see the nasty side of people who like to dislike somebody who makes me ... Me," he wrote Sunday.
"#SometimesIHateTwitter when it becomes a place to abuse people who uve never met never did anything to you but you still choose to be cruel," he added.
Liam told "all those horrible people who are going to be dicks and tweet her horrible stuff now just because i mentioned it" to "grow up."
He was quick to clarify, however, that he appreciates "all those people are who are nice" and said his girlfriend "often reads me nice things people say to her and it makes me smile love you guys."
Liam wasn't afraid to stand up for his lady, and Harry Styles wasn't fazed when his bandmates stripped him down for the fans!
During a Chicago show over the weekend, Liam and Zayn Malik ripped off Harry's shirt on stage. (If you'd like a peek, fast forward to the 2:09 mark in the video below.)
Unperturbed by the guys' laughter, a surprised Harry kept singing "What Makes You Beautiful," although the lyrics were barely discernible over the crowd's shrill screams.
