There was a time when YouTube makeup powerhouses Jeffree Star and Manny MUA (a.k.a. Manny Gutierrez) seemed to be undeniable BFFs, collaborating on collections, doing each other's makeup, and laughing off the haters together. Now, it seems the haters may very well be each other. As rumors about a fallout swirl, a seemingly intentional slip of the digital tongue by Star might have just confirmed that this former friendship has turned into the biggest beauty rivalry since Elizabeth Arden and Helena Rubenstein.

Revelist reports that, in a now-deleted tweet, Gutierrez wrote, "When your [sic] casually scrolling on tumblr and see an old friends nudes," apparently in reference to Star's boyfriend, Nathan. This prompted Star to reply, "isn't life a drag? never a dull moment on the internet! he says hi!" And many interpreted the tone as... not nice — especially when Star then tweeted again, repeating the phrase "LIFE'S A DRAG" and getting beauty-gossip sleuths' gears going.

Turns out, Life's a Drag has been trademarked as a makeup product name by Lunar Beauty, Inc., which is Gutierrez's brand, and fans are putting together clues — like his recent Lunar Beauty photoshoot with drag queens — that are leading them to believe it's the name of his highly anticipated eye shadow palette. However, Gutierrez hasn't publicly revealed that name and probably wasn't hoping to do so via a Twitter feud. What Gutierrez has revealed is a photo of crushed pigments, which fans also believe may be the palette.

He might have also inadvertently revealed just how bad things have gotten between himself and Star, who kept subtweeting into the week:

Gutierrez, on the other hand, appears to have moved on, tweeting about gray hairs and new projects — and hopefully some more information about that palette soon.

Let's look back on Manny and Jeffree's happier days:
