New Balance is waging a sneaker war against one of the most iconic names in high fashion ... claiming Karl Lagerfeld ripped off its trademark sneaker for his new shoes.

According to a new lawsuit -- obtained by TMZ -- New Balance claims Lagerfeld is using a block capital letter "K" on an otherwise identical shoe design. NB claims this creates confusion.

Serena Williams is the only -- repeat ONLY -- woman alive who could pull off crashing a beach wedding while wearing a leopard print one-piece swimsuit.

Williams was in Miami this weekend when she stumbled upon a beach wedding ... and jumped right in. She posed for a few pics with the bride and groom ... all while yelling out "Wedding crasher!"

Halle Berry had time to call her lawyer, and time to file a lawsuit -- but she is fresh outta time to sit down for a deposition in HER case against a watch company ... because her vacay is calling!

According to docs filed in the case, ToyWatch -- which Berry is suing for selling watches with her name on them without permission -- claims Halle is blowing off its request to take her depo.

The watch company claims Berry first told them she would do it in May, but then backed out ... citing her busy work schedule, and a fabulous vacation she'd planned.

Halle's travel agent and lawyer need to get on the same calendar -- remember, she filed this $2 million suit. Halle is agreeing to sit for the depo in July, but ToyWatch says that's cutting it too close to the start of trial ... and would put its lawyers at a disadvantage.

Justin Bieber and his abs hung out with billionaire Sir Philip Green aboard his yacht in Monaco this weekend ... appearing quite chummy.

It's a funny pairing -- Green made his fortune off clothing (Topshop) ... and JB rarely wears any.

Only one guest at Kim Kardashian and Kanye West's wedding truly touched the couple -- with a booger finger -- and still got the nod.

We were shocked to see this pic of ex-Vogue honcho Andre Leon Talley (sweet cape) leaving Florence with all of Kimye's other wedding guests Sunday morning ... considering his nose pick faux pas with K & K at the Met Gala a few weeks ago.

Ya can't say Kim holds a grudge -- and we ain't sayin' Andre's a golddigger, but ...

Justin Bieber strolled into a fancy formal party in Cannes ... but he was dressed for a backyard barbecue on the Florida panhandle.

Bieber was a guest at Roberto Cavalli's (see below) annual Cannes yacht party, where everyone was dressed for a high-end evening ... except for the Biebs.

While John Travolta showed up in a tux, Bieber opted for a denim vest with a jersey, a pair of baggy shorts, super casual slippers, and no socks.

On a positive note ... he was wearing a shirt.

On a different note -- Justin offered this review of his outfit ... "I know I look fly but s***."

Sarah Jessica Parker going to the White House meant code red for the First Lady -- as in what the hell to wear when a fashion icon comes over? So, did Michelle Obama dress to impress?

We asked SJP, and the jury is still out! For us, not Sarah ... she totally caved under pressure.

Taylor Swift is a hell-raisin', fast-drivin' bad girl -- at least in the eyes of a clothing company that's suing her for allegedly ripping off its brand to sell her own merchandise.

TMZ obtained a copy of the lawsuit filed by Lucky 13 owner Robert Kloetzly ... and in the suit he accuses Swift of intentionally jacking his biz. Kloetzly says he's been marketing clothes and accessories to a young rock 'n roll crowd for 20 years, but now Swift is slapping "Lucky 13" on her own clothing line.

The allegation is ... Taylor is confusing the marketplace. In the docs, Kloetzly describes her as a tatted up singer who likes "fast cars and dangerous men who drive them inappropriately" -- and adds that's the same demo his company targets.

In the suit, Kloetzly goes on to claim Taylor's music video for "I Knew You Were Trouble" could be an ad for his Lucky 13 ... because it "depicts stylish, attractive, tattooed individuals in provocative situations."

Nobody f***s with the Hells Angels -- even in a court of law ... just ask Young Jeezy who's agreed to pay off the feared motorcycle club to settle their lawsuit against him, TMZ has learned.

We broke the story ... the Angels sued the rapper for allegedly copying their Death Head logo and slapping a knockoff version all over Jeezy's 8732 clothing line.

Apparently Jeezy was rattled enough from the lawsuit to almost immediately yank the items in question off the shelves.

So now we've learned the case has settled ... our biker sources say Jeezy coughed up some cash. As for how much, we're told "at least enough for some beers for the boys."

Jeezy's rep says the rapper is happy with the settlement.

As for the Hells Angels, they simply told us, "We always get what we want." True that.

CeeLo was NOT scammed into buying a fake designer watch for $34,000 -- despite a "watch expert" calling it a hideous counterfeit -- so says the jewelry company that crafted the piece ... and now wants a public apology.

Avianne & Co. fired off a cease-and-desist letter to the guy behind the popular Instagram account FakeWatchBusta -- because FWB recently posted a pic of CeeLo's custom 20-carat diamond-studded Panerai from Avianne, and outed it as a bad "fake."

FWB went so far as to add the following caption: "I really hope #CeeLoGreen said “HELL NO!” when he saw the ugliest custom fake #Panerai watch in the world ... The crown guard must have been removed with a hammer and then reattached upside down."

Avianne demanded the CeeLo post be taken down immediately and replaced with an apology ... as well as a comment saying the watch is in fact 100% real.

The photo has since been deleted from Instagram, but so far ... no apology's been posted.

Fun fact: Avianne is the same company that made Ciara's 15-carat diamond engagement ring.

Kim flashed her engagement ring for photogs ... and then she gave 'em the same rearview wedding guests will see walking down the aisle -- and it's glorious.

Hero Cat is on the attack again, but instead of a dog ... this time she's taking down a thong bearing her now famous nickname.

The owners of Tara -- aka Hero Cat -- tell us a friend of theirs opened a web store to help them capitalize on the national craze, but they had no idea the gear would include a thong with a paw right over the kitty zone.

Erica Triantafilo says she was shocked to see "Hero Cat" slapped on lingerie because she feels it's a bad example for kids -- so she went on a panty raid ... shutting down not only the thongs, but the whole online shop by Friday afternoon.

Jay Z was ferociously assaulted by Beyonce's sister Solange  ... who was wildly kicking and swinging at him inside an elevator ... and the attack was captured on surveillance video ... obtained by TMZ.

According to our sources, it all went down at a Met Gala after party last week at the Standard Hotel in NYC.  In the video ... Jay Z, Beyonce and Solange step into the elevator ... and then Solange goes crazy, screaming at Jay before unleashing a violent attack.

A large man -- who appears to be a bodyguard -- attempts to hold Solange back, but she manages to connect at least 3 times.  At one point Solange throws a kick and Jay grabs her foot, but never attempts to strike her.  Beyonce stands by without getting physically involved.

And this is interesting.  When you look closely, you see the bodyguard hit the emergency stop switch on the 12th floor -- mid fight -- presumably to keep the fight private.

At one point, Solange smacks Jay with her purse ... spilling the contents all over the floor of the elevator.

Eventually the group exits the elevator ... but not before Solange takes a few last shots.

All three walked out of the building together -- Solange looks pissed -- but while Bey and Solange get in one car ... security walks Jay to a different one.

It's unclear what triggered the fight.

Miley Cyrus recovers like no other -- after nine days in a hospital bed she hit the London club scene with the perfect night nurse ... legendary party girl Kate Moss.

Miley sported her best bra and leggings as she strolled into her hotel -- around 3:30 AM, according to paps -- after a night out at Madame Jojo's nightclub in SoHo.

You might recall ... even if she doesn't ... Miley had an extended hospitalized stay last month after what her peeps said was an allergic reaction to antibiotics.

She canceled several tour dates as a result.

Former Vogue honcho Andre Leon Talley is definitely our pick of the week.

Talley dug deep during his interview with Kim Kardashian and Kanye West during Monday night's Met Gala ... and then touched the golden couple with his fool's gold.

It's unclear how much time passes before the dig and the touch, but Talley is clearly seen touching Kim's shoulder as he kisses her goodbye ... before using the same hand to shake Kanye's.

Madonna's not ACTUALLY a slutty attention whore who planned to expose her nipples at the fanciest event in the world -- literally dressed like Leeloo from "The Fifth Element" -- at least that's what she's saying now ... claiming the photo she posted online Monday was a joke.

Sources close to the singer tell TMZ, she was just kidding when she posted the photo with the caption, "What i wanted to wear to Met Ball but Anna [Wintour] said Not this year! So I'm gonna work on music instead?"

Our sources say Madonna didn't even have plans to go to the Gala ... she was in the studio Monday night during the event and will stay there all week.

This just in: Madonna is 55 years old.
