Coachella

Kesha is making Coachella her big, "I'm back bitches."

We've learned the singer will appear alongside Zedd during his Saturday night set. It's uncertain if she'll actually perform, but she'll clearly have something to say.

Kesha has steered clear of live performances since her Sony war erupted, so this is a big change.

It was Kanye West's worst nightmare ... taking the stage in front of thousands ... not being able to rant or even rap.

A$AP Rocky brought Kanye up on stage Friday night as the big surprise, but Yeezy's mic malfunctioned. You hear A$AP and backup music but no Kanye.

Paris Hilton was engaged in a massive cover-up at Coachella, while Kellan Lutz was engaged in anything but.

Joe Jonas is giving his crew the presidential treatment at Coachella -- hooking them up in the same celebrity palace where JFK is rumored to have hooked up with Marilyn Monroe.

We've learned Joe's staying at the Rancho Mirage mansion -- compliments of Airbnb -- where legendary crooner Bing Crosby used to live. It's 7,000 sq. ft of insane modern amenities, panoramic desert views and a master suite appropriately named the "JFK & Marilyn Monroe" suite -- since they used to ... y'know.

That room alone is 1,400 sq. feet!

We're told the place rents for $10k to stay there for a weekend and there are some ground rules. No smoking inside, 18 daytime guests and only 12 can spend the night.

A dirty dozen? Sounds like a good time.

Coachella is gunning for anyone who bought a VIP pass to rub elbows with the likes of Axl Rose or Slash ... because it might be illegal and the cause of a lawsuit.

Goldenvoice, the company that puts on the fest, filed a lawsuit Wednesday against events company Particle, and its owner Denise Kozlowski, for deceiving people it was authorized to peddle a package including a VIP, guest, or artist pass.

Coachella says it's the only one who can sell tickets for the fest -- and it can't have third parties scalping those tickets because it creates a huge safety risk for performers.

Coachella fans opting out of fancy hotels, condos or mansions ... can park their asses and their horses at a huge 3 day camping party.

Vestal Village is an invite-only camping party that coincides with the Coachella festival. VV is going down at a secret location in the desert outside Palm Springs -- but we've uncovered a few clues about the scene that's been planned.

For one, we're told there will be stalls to accommodate horses and horseback rides -- however, BYOH. There will also be an Olympic sized pool and a lake. Eagles of Death Metal are headlining the event, which is sponsored by Vestal Watch, Gevitta and Estrella Damm.

We're told they're expecting about 6,000 people to attend the massive Coachella after parties.

That's a lot of dung.

Hoodchella -- the upstart L.A. music festival -- isn't backing down from a fight with Coachella and vows to move forward despite a $100 million lawsuit.

Hoodchella CEO Kamil Al-Ahdali tells TMZ he's not even considering canceling his April event. Coachella sued Kamil, accusing him of jacking the 'chella name and riding the more famous festival's coattails.

Kamil says he has a trademark for Hoodchella and even registered it as an LLC. He thinks Coachella's lawsuit is just a case of the big guy bullying the little guy -- but Kamil says his lawyers are "not going to let Coachella punk Hoodchella at all."

The folks behind Coachella have issues with the hood ... which is why they're going to court to gripe about an urban version of the festival.

Hoodchella is set to go down in April in the City of Angels. It's being advertised as a 2-day festival featuring a bunch of DJs.

Coachella has certainly made a name for itself since it launched 17 years ago, and the people behind it say they own the name and changing a few letters isn't going to fly.

Here's what's strange. This marks the SECOND annual Hoodchella, and it doesn't appear the Coachella people objected the first time around.

But under the category "Better Late than Never," they've filed legal docs demanding that the folks behind Hoodchella change the name.

So who's playing drums when Guns N' Roses reunites at Coachella? Matt Sorum seems a likely candidate, which is why our LAX encounter was so important.

Slash, Duff McKagan, and even Axl Rose have signed on, but no word on the skins.

Check out the video ... we can't figure out if Matt's in or out.

Matt played drums from 1990 - '97. Frank Ferrer assumed the role in '06, but with former members reuniting, Matt could be the likely choice.

Kourtney Kardashian celebrated her 36 birthday Saturday night in Vegas with boyfriend Scott Disick ... and he looks less than enthused.

The bash was thrown at 1OAK. There was a pretty big crowd, sans all the other Kardashians. Kim's at home in L.A., Kylie's at Coachella with Tyga and Kendall.

Khloe was busy Saturday night throwing a shindig for her new group messaging app called Regroupd.

Khloe Kardashian is a good sister by all accounts, but there are limits to schlepping to every celebration when lots of loot is on the line.

Kourtney turns 36 Saturday and she's having a big shindig at 1OAK in Vegas. But Khloe will be ensconced at Coachella, where she's hosting a private party for her new group messaging app called Regroupd.

Khloe's rented out a big house in the desert, where she's expecting 100 celebs, who will be well fed. There will be 2 food trucks -- Coolhaus Ice Cream and Umami Burger.

Beer pong tables are at the ready, as is pool basketball.

Khloe will roam the backyard giving celebs tutorials on her app.

Given that the Kardashians now have more money than God, it's possible Khloe could take a private jet to Vegas after her party.

Jaden Smith and Paris Hilton got all gussied up Friday at Coachella.

Jaden's choice seems ... a little on the frumpy side, while Paris is going for the swank.

So we gotta ask ...

Kendall Jenner got lucky when she was turned away from a 21 and over event at Coachella -- she didn't bother trying to flash a fake ID because everyone knows she's underage -- but hundreds of other teenage scofflaws were humiliated in a series of fake ID seizures.

Festival security busted 354 IDs presented by kids who wanted to score drinks with the help of phony IDs. Although technically it's a crime to flash one, no one really gets prosecuted.

The bogus IDs are actually put to good use. They're sent to the California Dept. of Alcoholic Beverage Control so investigators can eyeball state of the art counterfeit documents.

Chanel West Coast pulled a Justin Bieber at Coachella -- minus the chokehold -- and flipped out on camera when security guards turned her away from a VIP area.

According to our sources, the rapper and "Ridiculousness" star was with her boyfriend and another friend Saturday when they tried to get into the "artist's entrance" area, which of course requires a special wristband.

Problem was ... she had the wristband, her boyfriend had the wristband, but the friend did not. Security wouldn't give in, despite Chanel dropping Drake's name and Young Money (that's her label).

She stormed off, but Chanel tells us she and her friends did make it through the proper entrance a short time later, and partied the night away.

Justin Bieber was kicked out of Coachella Sunday night, but not before he was placed in a chokehold ... TMZ has learned.

Bieber and his entourage walked to the artist's entrance where Drake was performing, when they were stopped by security and told the area was at capacity and they couldn't come in. Bieber and his crew showed security they had the proper wristbands to gain entry.

Eyewitnesses tell TMZ, Bieber argued with security, saying there was no way he could stand in a big crowd because he'd get bombarded by fans. Security wasn't having it and told him to leave.

We're told Bieber persisted and said he was personally invited by Drake and had been waiting all weekend to see him perform. Bieber didn't stand down and security was pissed.

At that point a Coachella staffer came up to Bieber and said she would escort him inside the artist's area. She grabbed Bieber by the arm and began walking him and his security team inside, when Coachella security came up from behind and put Bieber in a chokehold.

We're told Bieber's team got into it with security and the singer was then ordered to leave the festival.

Drake was not grossed out when Madonna planted a prolonged lip-lock on him at Coachella Sunday night ... his reaction was all about lipstick aftertaste.

Sources close to Drake tell TMZ ... he loved the kiss. As for whether the kiss was prearranged, Drake says it wasn't ... the plan was for Madonna to dance around him while he sat in the chair.

Drake says he was not banking on a transfer of the glossy stuff and that's why he blanched.

When you look closely at the video, it looks like whatever lipstick there is it's pretty colorless ... either nude or beige.
