Jennifer Lopez doesn’t always do her own stunts … but when she does, she makes leaping 20 feet off the hood of a car in 5 inch stilettos look easy … and TMZ has the footage.

It all went down in Downtown LA on Tuesday … sources tell us JLo’s filming a super secret national commercial campaign, set to air during the American Music Awards.

We’re told Jenny performed the stunt several times … she takes a running jump and flies through the air from the hood of one car to another … like she's straight outta the Matrix (Though she is wearing a harness, so it ain't like she's Jackie Chan).

Lady Gaga stole a page right from Heidi Klum's fashion playbook last night -- strolling New York City dressed as an old, feeble lady ... only problem is when Heidi did it, it was a Halloween joke.

Our photog tried to ask about reports she'll be singing in space -- but the pop star was so committed to the old lady role, she refused to break character ... and replied, "You're from space?"

The whole thing was bizarre -- but we gotta ask ...

Justin Bieber has officially KILLED his plans to create a clothing line called "Wild Kidz" -- but he's letting one of his old lackies munch on the scraps ... TMZ has learned.

Of course, "Wild Kidz" was that stupid catch phrase Bieber and his friends Lil Za and Lil Twist would shout while doing dumb crap like pissing in mop buckets and flipping off ex-Presidents.

Bieber's people filed paperwork to trademark the phrase for a clothing line back in September ... and it seemed like the brand was on the fast track to production.

But as we previously reported, Bieb and the Lils started having some problems with their relationship (Bieb kicked 'em out of his Calabasas home) ... and in October, Lil Twist made a play for the brand by filing a trademark application for the name "W.I.L.D. Kidz." (See what he did there?)

Clearly, a war was brewing ... but sources tell us Bieber is planning to wave the white flag because he's OVER the company -- and doesn't care enough to fight Twist for the rights to the name.

Ian McKellen has magic underwear ... and yesterday, he showed off his special tighty-whities during a theater performance in New York City.

Of course, the face protecting Ian's pooper is Gandalf from "Lord of the Rings" -- the character played by Ian in the LOTR movies.

Fun Fact -- the undies were actually a gift from "Watch What Happens Live" host Andy Cohen.

Mazel.

So ... Jaimie Alexander won the "Thor" premiere last night.

The 29-year-old actress -- who plays Lady Sif in the movie -- rolled up to the El Capitan Theater in Hollywood wearing a dress that BARELY covered her lady junk.

Asgard ... meet Ass-guard.

Perv.

The Hells Angels don't need baseball bats and chains to protect their image -- all they need is a good lawyer, which is exactly what they got to sue rapper Young Jeezy's clothing line ... claiming Jeezy's company jacked their iconic Death Head logo.

The fabled motorcycle club filed the lawsuit against 8732 Apparel for essentially reprinting the Hells Angels logo on jackets and hats ... and selling them for a massive profit.

The 8732 design isn't an exact rip-off ... but Hells Angels claims it's close enough to confuse people.

HA claims 8732 has already earned substantial profits from the bootleg merch, and the motorcycle club wants every last cent of that money.

The club is now suing for unspecified damages. It also wants a judge to force 8732 to stop selling anything with an HA-looking logo on it. Calls to 8732 were not returned.

The Louis Vuitton Don is no more ... Kanye West is now trashing the upscale brand for screwing their customers ... and claims he won't design for L.V. again.

Mr. West was on Big Boy's Neighborhood this morning on Power 106 in Los Angeles -- and put Louis on BLAST.

As you may recall ... Ye coined his nickname "Louis Vuitton Don" on his debut album "College Dropout." He also designed a sneaker collection for the luxury brand in '09.

But now Kanye says he'd turn the designer down, if asked again ... mostly because of the outrageous amount they charge for their products.

Check out the video to hear his full explanation.

FYI -- Kanye's Louis sneakers had a price tag north of $800 ... and he once sat front row with L.V.'s CEO during Paris Fashion Week to promote the shoes.

Justin Bieber ventured deep into the Guatemalan jungle to help a group of poor villagers construct a badly needed schoolhouse this weekend ... and TMZ has the pics.

After Justin performed in Guatemala City on Saturday, he joined up with Pencils of Promise -- an organization dedicated to building schools for communities in need.

JB was choppered into a remote area outside the city on Sunday ... where a makeshift construction crew was already busy putting up walls for the new school.

In a video posted on his blog, Bieber says the town was overrun with poverty -- "I'm not talking about poor, I'm talking about 10 people living in a little shack."

Inspired, Justin ditched his shirt and went to work -- grabbing a wheelbarrow and helping to build a wall for the school.

He also took off his shoes and gave them to one of the local children.

Afterward, Bieber says it was, "one of the most amazing powerful experiences of my life."

Bieber says the experience helped him grow as a person -- saying, "I feel like they helped me as much as I helped them."

Kim Kardashian started an ass-selfie trend ... 'cause after she shared her bikini-wedgie with the world ... ANOTHER wanna-butt celeb is following suit.

This time, the chick showing off her donk is Mercedes "MJ" Javid from "Shahs of Sunset."

It's definitely a change of pace from Kim ... and pro surfer Anastasia Ashley, who beat MJ to the punch with a butt-selfie last week.

Butt-selfies -- sometimes they're not all they're cracked up to be.

"Real Housewives of Beverly Hills" star Kyle Richards won't let 4 children stop her from slutting it up on Halloween -- in fact, the 44-year-old tells TMZ, she's already purchased her risque costume for 2013.

Richards was at an event in L.A. Wednesday night when we asked how sexy a mom should dress on All Hallows' Eve -- and Richards said she had ALREADY purchased her costume from Trashy Lingerie in L.A., a store famous for its slutty duds.

But she says she did restrain herself a LITTLE for the sake of her kids, adding, "I ended up with [a more conservative costume] because I am a mom."

Of course, "conservative" at Trashy Lingerie just means your ass isn't showing ... completely.

Looking like she accidentally got her head stuck in a giant block of moldy Manchego, Lady Gaga stepped out in Berlin earlier today, definitely not scrounging for attention.

She's been naked for Playboy ... and donned itsy-bitsy bikinis for Sports Illustrated ... so it's no wonder Stephanie Seymour wasn't shy when it came to trying on lingerie in Italy yesterday.

The 45-year-old model grabbed some racy outfits while shopping at Agent Provocateur in Milan with her 66-year-old husband Peter Brant ... and tried them on right in front of the store window. It was awesome.

FYI -- Peter Brant is a paper mogul who happens to be a frickin' BILLIONAIRE!!!

So, good for him ... and good for her.

Kanye West went full balls out during his concert in Seattle this weekend -- with a crotchel wardrobe malfunction, crazy masks and a cameo from Jesus!

KW's pants split right down the middle during one of his songs -- but Kanye didn't seem bothered and moved on like it was no big deal (It looks like he's got underwear on, so it wasn't like it was full dong exposure or anything).

But the real story is the facewear -- ya gotta check out the pics.

Kanye West has figured out a new way to idolize baby mama Kim Kardashian -- he's enshrined her on his t-shirt.

The rapper was spotted in Seattle yesterday wearing the shirt with Kim's face on it -- shortly before kicking off his Yeezus tour -- and he couldn't help but smile.

Which raises the question ... would you wear a t-shirt with your S.O.'s face on it? Sound off in the comments.

UFC newbie Andre "Touchy" Fili has a secret weapon for his debut fight tonight -- stained, old green underwear ... and the fighter is pretty confident it'll give him an edge.

Fili knows the underwear might turn some people off ... however Touchy's convinced they'll bring him luck -- since he wore them during his most intense amateur fights.

Sadly, Fili won't actually be wearing the crusty briefs -- they're too long for his new gear ... but Andre says they will hold down the fort in his hotel room during 166.

As for the drizzle stains ... he's had 'em a long time.
