Christina El Moussa's pissed her good looks are being used to hawk an anti-aging product -- she's only 33, but she says the real issue is she never endorsed it ... so now she's threatening to sue.

Christina's name popped up in an online campaign claiming she's the face of a skin care product line that's made her rich beyond her wildest dreams. It's one of those Internet ads you see dozens of times a day, but Christina says it's straight-up #fakenews -- all the quotes attributed to her are completely made up.

She's fired off cease and desist letters to a ton of companies and individuals warning them to take down the stories, or she'll sue. The problem is it's hard to track down exactly who's behind the campaign. Different versions keep popping up, but all have the same message: Christina's behind these skin products, buy here.

UFC strawweight Michelle Waterson -- aka the Karate Hottie -- doesn't like that fellow UFC fighter Pearl Gonzalez had to jump through hoops to get cleared to fight with breast implants ... and says all women with fake boobs should be allowed to fight.

The NY State Athletic Commission conducted a review into Gonzalez before UFC 210 once they learned she had implants -- but ultimately cleared her to fight.

Waterson -- who's fighting Rose Namajunas this weekend at UFC on FOX -- says breast implants are no big deal ... and as long as the fighter makes weight, she doesn't think there's any real problem.

Chrissy Teigen just helped one aspiring skin care expert by taking a huge load off her shoulders ... she's paying for the student's tuition.

The student, a woman named Mercedes -- a self proclaimed skin care expert -- recently reached out to her friends and family asking for help to pay a $6k tab for classes in order to get a license in esthetics and further her knowledge in skin care.

Luckily for Mercedes, Chrissy came across her posting and plunked down $5,605 ... the remainder of the balance with a message, "I've seen this be your passion for such a long time now. So excited to see you fulfill your dream!"

Awesome move.

Look out, Sex Panther ... Floyd Mayweather is now looking to conquer the smell game.

Kristen Stewart got rid of her mop in favor of a blonde buzz cut.

The "Personal Shopper" star unveiled her new hairdo Tuesday at her movie premiere in L.A. ... and gotta say -- we dig it.

Kanye West wants to go head-to-head with his famous sister-in-law ... diving head first into the cosmetic biz dominated by Kylie Jenner.

Kanye's filed legal docs declaring his intention to produce DONDA brand makeup, perfumes, lotions and other cosmetics. Donda, of course, is Kanye's beloved mom who passed away in 2007.

He'll be up against some stiff family competition. Kylie's cosmetics sell out within minutes ... some resell on eBay for 10 times the retail value.

Kanye's application to snag the DONDA cosmetics line is currently being processed but our sources say at this time he's only filed the paperwork in case something develops.

He's made it clear ... Kanye wants to be the new Martha Stewart, creating a lifestyle brand that includes credit cards, cars, wallpaper screens, furnishings, video games, amusement parks, hotels, fitness centers and healthy fast food.

So which one's gonna give Kim lip?

Fabolous has put his money where his mouth is by dropping $40k to fix his teeth, and the before and after pics show it was worth every penny.

Loso has rapped about the chip in his front tooth on 2001's “Right Now & Later On," and hinted he'd get it fixed, and that's just part of his dental woes.

He went full dental just before New York Fashion week and left with a set of 10 new veneers on his top grill.

NY dentist Mojgan Fajiram usually charges around $4k per veneer, so it definitely adds up.

As for the timing... we're told Fab wanted to treat himself to a belated 39th birthday gift.

One of Kylie Jenner's eye kits has become a real pain for customers who've filed complaints about chemical-induced headaches.

At least 15 people filed complaints within the past 2 weeks with the Better Business Bureau, claiming they smelled "chemicals and glue" when opening Kylie's Royal Peach Eyeshadow Palette.

Customers described the odor as "spray paint" or "paint thinner," and one said it stunk so bad she put the whole package outside her house. There's also at least one complaint of the makeup causing "a horrible headache."

The BBB tells us Kylie Cosmetics launched an investigation immediately and found an adhesive in the packaging was causing the smell. Kylie's company insists it's safe to use ... according to the BBB.

Kendall Jenner gave the audience a surprise with a turn at a New York Fashion Week show.

Kendall was strutting the runway for La Perla along with Jourdan Dunn, Stella Maxwell and Naomi Campbell, and stole the show in her sheer gown ... with a little help from her ass.

They called her "fat," "flabby" and worse ... but Lady Gaga has a message for all the trolls who body shamed her Super Bowl halftime performance ... GO BACK UNDER YOUR BRIDGE!!

The singer is finally firing back at the haters who pointed out that her stomach wasn't as rock solid as they felt it should have been during the show. It got pretty nasty and Gaga's fans have been at war with the trolls on social media ever since Sunday.

Now, Gaga is weighing in ... saying, "I heard my body is a topic of conversation so I wanted to say, I'm proud of my body and you should be proud of yours too."

She added, "No matter who you are or what you do. I could give you a million reasons why you don't need to cater to anyone or anything to succeed. Be you, and be relentlessly you."

"That's the stuff of champions. thank you so much everyone for supporting me. I love you guys."

Kylie Jenner's using her considerable social media capital to settle a potential legal war with the makeup artist who claimed KJ stole her photos to promote her brand.

We broke the story ... Vlada Haggerty threatened to take action against Kylie for ripping off her work. Vlada's lawyer claimed Kylie Cosmetics had a "history of taking Haggerty's original dripping lip art and passing it off as Kylie's."

The threat was enough for Kylie's legal team to swoop in, resolve the matter and now Vlada's getting something way more valuable than cash. Kylie's started plugging Vlada's signature makeup looks on her Instagram page. 84 million pairs of eyes checking out her work!

Kylie's camp had no comment.

Kim Zolciak is coming to daughter Brielle Biermann's defense denying the 19-year-old has ever had butt implants, despite what the Internet thinks.

Brielle posted a racy pic of her rump on Snapchat and many jumped to the conclusion that it was fake since she has posted video of her lip injections in the past.

However, Kim tells TMZ the proof Brielle's got natural cakes is in the rest of her body ... there isn't an ounce of fat to use for butt implants. Kim says Brielle's big ass comes from the gym -- she works out a ton.

Not to mention ... she's 19.

Michael Costello, fashion designer to the stars, is slimming down to comply with what he calls the industry standard -- "skinny bitch" -- and he's using lasers to do it.

Michael finished 4th on Season 8 of "Project Runway" and told us about the moment at a friend's wedding when he knew it was time to fight the fat. One button can change a lot.

He went to Dr. Rollins at Elite Body Sculpture in Bev Hills on Friday to get Airsculpt Laser Liposculpture on his stomach and waist. The procedure uses lasers to soften up your fat, then they vacuum it out. Michael says he dropped 2 sizes instantly.

Michael recorded the good doc going to work on him. Check it out ... if you can stomach it.

Kim Kardashian is worry-free in Dubai -- with lax security and a fair amount of cleavage.

Kim strolled through Atlantis hotel Thursday and for the first time in months, her security team was further than an arm's length from her. She's lost the baggy sweaters and grunge ... for sure.

The trip was originally scheduled for last October, where she was going to do a makeup tutorial her makeup artist was throwing. So this is a makeup makeup tutorial.

Kim Kardashian says the coast is now clear because cops in France have nabbed a bunch of people who allegedly robbed her ... so she's off to Dubai.

Kim breezed through LAX with Scott Disick and 4 security guards for the 16 hour flight.

Justin Bieber is covering an old hit ... his 2010 hairstyle.

The Biebs looked like his younger self while grabbing lunch at the Montage Beverly Hills, proving everyone loves a throwback these days.

Hey ... anything's better than the 'Where's Waldo?' look.
