This is a battle royale! All of these grown adult A-listers above are going at each other on Twitter -- making social media a veritable battleground/confessional/therapy session. What the heck?!

It started with Kanye dissing Travis Scott for participating in Drake's undercover messages about Ye on "Sicko Mode." On Thursday, Kanye posted a text he received from someone named "Free" (probably a music producer), acting as a middleman between Ye and Drake to request that Kanye clear the rights for Drake's single "Say What's Real" which appeared on West's 2009 album 808s and Heartbreaks. Kanye used it to illustrate how "fake" the rappers' beef is with each other -- "faker than wrestling." Then he Tweeted that he's still waiting for Drake to apologize for his lyrics in "No Stylist" that reference Drake not wanting his girlfriends to wear Yeezys. "Been trying to meet with you for six months bro. You sneak dissing on [brother-in-law Travis Scott] records and texting [mother-in-law] Kris [Jenner] talking bout how’s the family." He went on to address his self-admitted mental issues: "Sending purple emojis when I’m dealing with mental s—. I need my apologies now. Not through Scooter [Braun] either. Not through Travis."

Enter Travis Scott -- Kylie Jenner's baby daddy -- who's in the middle of this mess for collabing with Drake on the single "Sicko Mode." The track "sneak disses" Kanye in the lyrics, "Jesus Christ (Yeah), checks over stripes (Yeah) / That's what I like (Yeah), that's what we like (Yeah) / Lost my respect, you not a threat" -- checks being a reference to Nike and stripes to Adidas. Drake slammed Travis, writing: "I used to bring Travis with me everywhere with me Im an inspiration to both him and Drake." He went on: "I heard Drake had more bars dissing me that were removed,' and then reminded, 'Trav is my family and let this met throw sneak disses at me for clout." He went on to say, "F*** that sickomode song Family first and always."

Drake responded with a series of laugh/crying emojis on his Instagram story. And apparently Trav called Kanye to which Ye responded on Twitter: "I hit Trav earlier today. Now he just hit me. More threats. I have a problem with sneak dissing. All positive energy I got love for everyone. Just don’t sneak diss or diss at all. I paid the dues for all weirdos. I love everybody all positive energy. No one that is a musician should ever diss me. My existence is for the rights of all artist."

Then Kim Kardashian jumped into the mix to defend her man, posting: "Never threaten my husband or our family. He paved the way for there to be a Drake."

Whew! Now who could possibly be LESS involved in all his mess than ... Ariana Grande?! Well, she injected herself, Tweeting: "Guys, i know there are grown men arguing online rn but miley and i dropping our beautiful, new songs tonight,” she tweeted. “If y’all could please jus behave for just like a few hours so the girls can shine that’d be so sick thank u." Kanye replied, "I know Ariana said this to be cool and didn’t mean no harm but I don’t like even slightest level of slight commentary from someone I know loves and respects me." And he went on: "All of this foolishness weighed on my mental health so @ArianaGrande you know I got love for you but until you’re ready to really make sure everyone’s ok don’t use me or this moment to promote a song."

Ariana promptly deleted the Tweet but it had already trickled down to her ex Pete Davidson who also injected himself into this by writing: "We need people like Kanye. No one should ever point fingers at you for your bravery in speaking about mental health. I’m seriously disgusted."

Grande apologized, but with a twist: "with all due respect, i don’t need to use anyone to promote anything. period,” she wrote. “i was making a comment ab what men were doing at the time vs. women ... it was a joke which i understand now was probably insensitive. i apologize if i was in any way triggering and hope u feel well today."

Davidson, who's been open about his borderline personality disorder wrote on Saturday: "i really don’t want to be on this earth anymore. i’m doing my best to stay here for you but i actually don’t know how much longer i can last. all i’ve ever tried to do was help people. just remember i told you so." Whoa! Calm down, Nelly! You're not even involved in this!

But that didn't stop his ex from rushing to his side, for fear she could lose another boyfriend. The pop star apparently went to the SNL studios in New York and even Tweeted about it from the sidewalk outside the building: "I’m downstairs and I’m not going anywhere if you need anyone or anything. I know u have everyone u need and that’s not me, but i’m here too." She went on: "man i’m so sorry i told a dumb joke. i really didn’t mean any harm. all i want everyone to be healthy and happy. so desperately. please. my god."

Ariana's now deleted all of this and Pete's deleted his Twitter account (again). Meanwhile, Kanye says he's now met with Travis and all is good. He's also still Tweeting like crazy ... and saying he's not crazy ... or that he IS crazy and it's a good thing because he's off meds and off alcohol and feeling like himself again.
