The Kardashians

Kylie Jenner's NYC tattoo artist says authorities will NEVER bust him for letting an unlicensed Kylie ink him up, but if they do ... he's ready and willing to pay the fine.

Bang Bang is the guy who gave KJ a new tatt on Monday night, before putting the tattoo gun in her hands. Kylie posted video of her handiwork, and as we first reported ... the NYC Health Dept. was looking into possibly fining him, anywhere from $300 to $1,000.

But he tells TMZ, they can't fine him because he and Kylie weren't caught in the act. He adds he's never been fined for letting celebs tattoo him. In fact, he believes he's doing a good deed -- "Isn't it best to learn under a licensed professional who can supervise?"

Bang Bang adds, "FYI, I'd pay $1,000 to let Kylie tattoo me any day of the week."

We're sure he's not alone.

Kylie Jenner went out and got a tattoo artist license -- is what you might think after watching this video, but she didn't ... and now a NYC tattoo shop could be in big trouble.

Kylie hit up Bang Bang Tattoos and got some fresh ink -- carefully placed on her ass/hip area. Totally kosher. The problem is KJ also took control of the ink at one point.

She posted a video of herself handling the tattoo gun, and tatting a crown and a "K" on the artist's leg. The artist fully consented, but it's a Health Dept. violation to let an unlicensed person operate the gun.

The NYC Dept. of Health and Mental Hygiene is aware of Kylie's video, and we're told Bang Bang will at least get a warning -- and possibly a hefty fine. Penalities can be anywhere from $300 to $1,000.

Kris Jenner's birthday party did not disappoint ... it was every bit the $2 million bash, with a Great Gatsby theme right down to the cars and the flappers, fireworks and a whole lot of food.

Hundreds of people showed up at The Lot in West Hollywood Friday night. The first order of business was fireworks ... they went off at around 6 PM and lit up the skies from the beach to downtown L.A.

The Kardashian brood was there in full force -- we're not sure about Rob and although Caitlyn was supposed to be there, we didn't see her. Khloe had no problem getting down on the dance floor with makeup artist Joyce Bonelli.

Melanie Griffith, Kyle Richards , Lisa Rinna, Harry Hamlin, Boy George, Tommy Hilfiger and lots of others joined in the festivities.

Kanye sang happy birthday ... which is always awesome.

Safe to say she had a good night.

Kris Jenner's Great Gatsby themed 60th is already on the road to being an epic bash ... crews are hauling in period cars to make the night authentic and awesome.

Check out the pics we got of a trailer hauling two old school mobiles -- a Caddy and a Rolls -- hours before Friday night's party.

Kris Jenner, along with Kim, Khloe, Kourtney, Kylie, Kendall and Tyga ... all took a trip to Cedars-Sinai Medical Center in L.A. Friday to wish Lamar Odom happy birthday.

Lamar, who turns 36 today, is alone and laid up ... he's been there since October 19.

We're told the family will hang out in his room for a while. We're also told a select group of Lamar's longtime friends are also there. Our sources say none of Lamar's friends who are there were part of Lamar's drug crew.

As we reported, the Kardashians are throwing a $2 million party for Kris' 60th birthday Friday night.

Kim Kardashian's less than 2 months from popping, and yet she's looking more like she had a big lunch ... than a woman on the verge of giving birth.

We got these pics of Kim shooting for "Keeping Up with the Kardashians" Thursday evening at Maria's Italian Kitchen in Calabasas. She was hanging with pal Jonathan Cheban, which isn't weird.

What IS weird is her apparently vanishing baby bump!

When the Kardashians throw a birthday party they go big, but they're about to outdo themselves with Kris Jenner's 60th ... it's gonna set the klan back $2 MILLION, TMZ has learned.

All six kids chipped in for her party Friday night ... even Rob, whose name appears on the invite. They rented a giant soundstage in West Hollywood, which will be filled with 300 people.

The theme is Great Gatsby, which is perfect ... the book's themes toy with old money vs. new money and the perception of class in society, so expect a lot of champagne and fireworks.

We're told there will be huge stars performing ... though no one's talking.

Our sources say there will be big, big celebs attending, in addition to the usuals ... Kanye, Tyga, Kris' close pal Melanie Griffith, bf Corey Gamble and Caitlyn.

Just kidding about the fireworks ... maybe.

Kylie Jenner wasn't about to let the world celebrate her mom's 60th birthday without an attention grab, so she pulled out the big guns -- a tank top, underwear and that's it.

Just like mama taught her.

Kim Kardashian and the fam have an unlikely ally in Nashville, and his name's Steven Tyler ... who's ready and willing to make room for their asses on any stage they want.

Steven was leaving a CMA after-party when we asked him about Rebel Wilson going off on the Jenner/Kardashian clan ... blasting them as talentless hacks.

Check it out ... the Aerosmith frontman did NOT hesitate to tell us where he stands on the issue.

Sorry, Rebel ... Tyler's never been one to turn down hot chicks.

Kardashian family matriarch Kris Jenner turns 60 on Thursday ... but she certainly doesn't look it!

You gotta love the honesty from Eric Dickerson ... who says if he was a young, star athlete today -- there's no way he'd date just one woman ... he'd try to sample ALL of the Kardashians!!!

This clip is awesome ... the NFL Hall of Famer tells TMZ Sports, athletes should go out and have a good time and enjoy ALL of the perks of being a celebrity ... as long as they do their job.

But when we specifically asked about Kim, Khloe, Kendall and the rest of the K-squad, Dickerson's answer was the best.

"Let me put it to you like this here ... if I was in my 20's, I'd be dating them all."

Kris Jenner and her agent strung along videogame developers just long enough to rip off their ideas and create the cash cow known as "Kim Kardashian: Hollywood" ... according to a new lawsuit.

Kung Fu Factory, the developer, says it was contacted through a rep for the Kardashians in 2011, saying they were interested in creating a Kardashian-themed videogame. According to the suit, obtained by TMZ, Kung Fu says it did the deed ... presenting a proposal for the game to Kris' rep.

Kung Fu says its version was very specific ... including everything from how Kim, Khloe and Kourtney's characters would look, to how the game would be played. However, months went by without any final decision from the Jenner/Kardashian camp ... until Kung Fu finally heard the game talks were "dead."

The videogame jocks say "Kim Kardashian: Hollywood" -- released in 2014 -- has many similarities to their copyrighted proposal.

Kung Fu wants unspecified damages, including profits from the game ... which are huge. Forbes estimated it would haul in $200 mil in its first year alone!

Metta World Peace says he and Kobe Bryant both tried to save Lamar Odom from going down a dark path ... and were FURIOUS when they learned he overdosed in a Nevada brothel.

Rebel Wilson went off on the Kardashians Wednesday, calling them a no-talent family and making it clear ... she feels they do not deserve the fame they achieved.

Rebel appeared on "The Kyle and Jackie O Show" on KIISFM in Australia, and revealed she passed on a chance to present at the VMAs with Kendall and Kylie. She seems super resentful, saying, "What they stand for is totally against what I stand for."

Kendall Jenner looks like she's starring in a remake of "American Graffiti" ... tooling around in a classic, awesome '57 Corvette Stingray.

Kendall was behind the wheel as BFF Hailey Baldwin rode shotgun Tuesday in Bev Hills.

We're told the car was a present for Kendall's 20th birthday ... a present she gave herself.

Fact is, 1957 was one of the most epic years in auto design history, with the Vette and T-Bird leading the pack.

Unclear what it set her back, but $70k would not be out of the question.

Kendall Jenner can draw a crowd, which she did in impressive fashion at The Nice Guy in WeHo for her 20th birthday bash.

Gigi Hadid was one of the first to show, which is appropriate because of her new bond with Kendall ... we've confirmed they'll both be on the runway for "Victoria's Secret Fashion Show."

Also present ... Kim and Kanye, Ruby Rose, Khloe and Kourtney, Kylie and Tyga, Drake, Miguel, Lil Za and Jaden Smith.

If you get to the end of the clip, you'll see Kendall's birthday cake about to be thrown in a dumpster.
