Everyone's rallying behind Tati!

Jeffree Star entered the fray in the Tati/James Charles feud, writing on Twitter, "There is a reason that [boyfriend] Nathan [Schwandt] banned James Charles from ever coming over to our home again. There’s a reason why I haven’t seen him since @GlamLifeGuru’s birthday in February. He is a danger to society. Everything Tati said is 100% true." The beauty YouTuber also went off on Charles' younger brother Ian Jeffrey, writing, "Why does everyone act so tough over the internet?,” to which Star replied, “Why is your brother a predator?? Why’d you really move back to NYC? Exactly. Shut the f—k up." He has since deleted the posts -- not sure why.

Long story short, the beef began when Tati, the Halo Beauty creator, slammed Charles for promoting products that compete with hers after SHE MADE HIM FAMOUS! She vlogged about her the teenage millionaire has no right to complain about his life or anything else, after she launched his success and he proceeded to ice her out and even work directly against her.

That's not the only problem Tati and basically the entire Internet has with James Charles. The makeup tutorial teen has been accused of trying to turn straight men gay -- making it a mission to go out and get straight dudes to hook up with him on camera. Star and Tati call him a "predator," but he's got one YouTuber friend who's supporting him, Gabriel Zamora.

Gabriel says Tati's leaving out some crucial info -- that guys are hitting up James in his DMs and he's just flirting back but that he's not actively going after straight guys.

What it all boils down to for now is subscribers -- James Charles has lost over 3 million and Tati's GAINED the same number. Ouch! James, haven't you ever heard the old adage, "Don't bite the hand that feeds you?"
