Fifth Harmony sent a clear message that if you mess with one of them, you mess with them all. Just ask The Vamps.

Some serious Twitter drama broke out on Thursday after the British boy band made some comments about 5H member Lauren Jauregui. While sitting down with Australia's Take 40, Vamps member Brad Simpson was asked about his rumored relationship with Lauren.

"I was April to December," he responded about their time together, but then James McVey jumped with this: "We all had a bit of a go."

Yikes. Well, after that comment, it didn't take long for the girls of 5H to speak out and show them who's "Bo$$."

Normani called out those "little boys" for being out for being "immature."

While Dinah tweeted out a link to Big Sean's "I Don't F-- With You," and states exactly what she would say to the guys if she had a chance.

Camila also got in on the action tweeting the hashtag #LaurenIsOurPrincess and calling out the foursome saying that the "amount of sexism and immaturity is astounding."

James clearly heard about the online firestorm issuing an apology claiming that his comments were "totally misinterpreted."

Lauren took to Twitter early Friday morning and while she didn't address the situation directly she did let everyone know that their supports "means a lot."
