Live Nation is hell-bent on making sure no one’s peddling bootleg John Mayer t-shirts outside Madison Square Garden next month when his show rolls through town.

The company just got a temporary restraining order banning street vendors from manufacturing, distributing or selling any merch with Mayer’s logo or likeness 4 hours before and/or after his April 5th show within a 4-mile radius of the venue.

We’re told the NYPD has a special task force to deal with these types of issues, called the “MSG Team,” who will seize any counterfeit gear.

Good news is there’ll be plenty of official merch to purchase … for way more.

Forever 21 needs to step the hell off Rihanna‘s coattails, and her footwear designs for that matter … according to Puma which says the retail giant is straight ripping off RiRi.

Puma is suing Forever 21 in federal court, accusing the company of illegally knocking off several shoes Rihanna helped design for Puma’s “Fenty” label. According to the docs, Forever 21 has copied at least 3 of Puma and Rihanna’s designs — the Creeper, the Bow Slide and the Fur Slide.

Rihanna’s served as Women’s Creative Director and brand ambassador for the sportswear co. since 2014. Puma openly admits in the lawsuit, it keeps volume low on her line in order to create demand for the “luxury products” — a strategy it claims Forever 21 screws with its replica shoes.

Forever 21′s whole “business model is based on trading off of the established goodwill of reputable, name-brand companies, such as Puma” … according to the suit.

Translation: They’re biting our style because they know it’s hot.

Puma points out it holds patents and copyrights for the shoe line. It’s suing to immediately shut down sales of the “knocked-off” gear, and for ALL Forever 21′s profits from them.

Marshawn Lynch is making moves … signing a smokin’ hot Victoria’s Secret model to be the face of the new women’s workout line for his Beast Mode fashion brand.

Lynch announced Gracie Carvalho has joined the B.M. team as his first “brand collaborator” — on a workout collection called “Gracie x Beast Mode.”

The company says Lynch handpicked Gracie after meeting her in 2016 and “comparing notes about their respective workout routines.”

Gracie’s no joke … she’s been Muay Thai fighting for years and flies out to Thailand to train with the best in the world. 

Congrats!

Ivanka Trump‘s company is crushing some of its competition so badly, she’s now facing a lawsuit from one of the companies on the losing end.

Modern Appealing Clothing thinks President Trump‘s daughter is getting an “unfair” boost in sales — allegedly several hundred percent — based on the fact she’s now the First Daughter. The company points to huge public spectacles like Kellyanne Conway‘s February appearance on FOX News, where she gave a shout-out to Ivanka’s clothing line.

In docs, obtained by TMZ, the company says even the prez is “exploiting the power and prestige of the White House” simply to help his daughter’s company make a few bucks.

Modern Appealing filed a class action lawsuit, demanding Ivanka’s company stop using her political ties to improve her bottom line.

Nordstrom famously pulled Ivanka’s shoes, citing lagging sales numbers — but Modern Appealing Clothing seems to think she’s doing just fine. Too fine, in fact.

You know that furry getup Carmelo Anthony rocked to the Knicks game Tuesday night? It was custom-made … and it was expensive! 

TMZ Sports spoke with Nadeem Waheed – owner of Daniel’s Leather in New York — who says Melo dropped $5,000 on the American sheepskin shearling with cross fox fur … and added the $500 hat to match.

Melo’s been a regular and loves the threads … so you probably haven’t seen the last of it! 

Robert Blake‘s new chick is so ride or die … she’s already dressing like him.

Robert and his fiancee, Pamela Hudak, wore matching caps, denim and cowboy boots Sunday as they headed out to dinner in Bev Hills.

We broke the story — the couple got a marriage license last week.

No date yet for the wedding, but they’ve known each other for decades — as reflected in their wardrobe choices.

Kim Kardashian‘s pretty transparent these days … quite literally, actually.

The reality star showed off some serious skin in this see-through lace gown while filming a cameo in “Ocean’s 8” in downtown L.A. Serena Williams and Sports Illustrated model Kelly Rohrbach also rocked some fancy threads for their cameos.

It’s interesting … the flick’s about a jewelry heist targeting celebs.

Kim, of course … well, you already know.

Kendall Jenner, Bella and Gigi Hadid just proved modeling does require some brains — or at least planning a modeling show with a rocket launch does.

The 3 of ‘em were in Paris this week strutting around with Chanel gear on, and with a giant rocket ship behind them — which took off at the end of the show.

The faux spacecraft only got about 30 feet in the air — still kinda cool to see hot models coming together in the name of science!

Well, fancy clothes with a science-ish backdrop, anyway.
