If there's one thing we've learned from following the One Direction guys on Twitter, it's that they're not afraid to strike back when people get a little too sassy.
And of course, we're not referring to fans. No, no – the times the 1D boys got most heated were when they got into a war of words with other famous stars. Harry Styles, Niall Horan, Liam Payne, Louis Tomlinson and their former bandmate Zayn Malik have all had their fair share of social media feuds, and we are breaking them all down for you.
We know what you're thinking – some of the One Direction cuties are more likely to get into social media wars than others. Like who in their right mind could ever start a fight with Nialler's kind, genuine soul? However, he did have a little awkward exchange of tweets after he trash talked a professional rugby player's attitude. But hey, he was just making an observation.
Click through the gallery to see all the heated times the One Direction guys got into serious fights on Twitter.

Louis Tomlinson feuded with Thomas Parker.
Remember when The Wanted and One Direction were in a huge fight? Well, in the midst of all that drama, Louis and Thomas had a pretty heated exchange on Twitter.
Thomas implied that Louis was desperate to get into their band, but the 1D singer was quick to clear things up. “Pal, we both know I wouldn't waste my time auditioning for your band. You humour me with your bad boy persona,” he tweeted.
The two of them went back and forth with the insults, and even their girlfriends and Liam got involved. YIKES!

Liam Payne feuded with Boy George.
The feud started when Boy George lashed out on Twitter about Liam being disrespectful to his niece on the red carpet. “Top marks to Harry Styles for stopping for a picture with my niece and Bollox’s to Liam and the disrespectful wander of a minder!” the singer tweeted.
But then Liam responded, “Now now boy lets not tell porkies firstly thanks for getting my name wrong three times secondly then asking me where is liam?...akward then when you finally got it right saying you wanted Niall instead. if you would have asked me for a picture i would have stopped bro I just did what you said and pointed Niall out for you so u just keep wearing ur strange hats and enjoy yourself my little Georgie pie... It's still not cool you just look weird.”

Niall Horan feuded with Mike Phillips.
While the One Direction singer was supporting his favorite rugby team, he totally dissed Mike Phillips when he tweeted, “Mike Philips is like a child throwing his toys out of the pram! his attitude is terrible, looks like a right arrogant idiot.”
But then Mike saw the tweet and basically ignited the feud, dissing all of the One Direction guys along with Niall. “Come down to training in the week big boy. Bring the rest of The Beatles with you,” the player tweeted. And things got even more heated when Rob Kearney jumped in to defend Niall. Talk about drama!

Niall Horan feuded with Piers Morgan.
The TV host dissed Niall on Twitter after he tripped and fell carrying golf clubs at the Masters Golf Tournament. “So far @NiallOfficial, I've watched you hit it in the water & fall over. Think I'll go to bed before things get even worse! #Augusta,” he tweeted.
But then Niall responded, “When was the last time you caddied at the par 3 at the masters piers? Oh yeh never ! Back to bed old man!”

Louis Tomlinson feuded with Naughty Boy.
Soon after Zayn Malik left 1D, rumors started to circulate about him working with Naughty Boy. But just a few days later, the producer confirmed the news by posting a picture of him and Zayn in the studio, and Louis was not happy about it. “Wow @NaughtyBoyMusic you're so inconsiderate pal, seriously how [expletive] old are you ? Grow up ! #masterofallwisdom,” he tweeted.
He also subtweeted about Naughty Boy’s photo, but the producer had a comeback of his own. “Some people can't even sing.. but who's complaining when there's auto tune eh,” he tweeted, clearly referring to Louis. But then the One Direction singer responded, “Jesus forgot you were such an in demand producer .... How does it feel to be riding on the back of someone else's career?”

Louis Tomlinson feuded with Zayn Malik.
They feuded not just once, but TWICE on Twitter. At one point, Zayn got involved with a feud that started between Louis and Naughty Boy when he tweeted, "remember when you had a life and stopped making [expletive] comments about mine?"
And on another occasion, Louis jumped in to defend Calvin Harris when things got heated between him and Zayn. He actually favorited one of Calvin's tweets while they were feuding!

Harry Styles, Louis Tomlinson, and Liam Payne feuded with Piers Morgan.
Okay, so this wasn't exactly a super serious feud — it was really all in fun. But when Piers made an offensive comment about David Beckham, Harry, Louis, and Liam, all came back at him to show their support for the soccer player.
Piers then tweeted, "Well sign him up for the group - bet he sings better than he plays now." OUCH. But the boys didn't give up that easily. Harry even called on Simon Cowell for help when he tweeted, "Hiiii @SimonCowell can you tell @piersmorgan to leave us alone please? He's being nasty.."
