One Direction

British rockers "Def Leppard" claim "One Direction" ripped off one of their biggest hits ... and get this ... they're flattered.

Def's legendary one-armed drummer Rick Allen tells us any fool can hear the similarities between their 1987 hit "Pour Some Sugar On Me" ... and 1D's tune, "Midnight Memories."

Maybe the real reason for calling off the lawyers ... Allen seems to admit he's done to other bands what 1D did to his. Listen to him ... it's hysterical.

Still, we gotta ask ...

There may be a little nip in the air at the American Music Awards Sunday ... TMZ has learned Kendall Jenner will be presenting.

The gig comes on the heels of the 18-year-old's very adult Instagram photo.

We're told she'll be presenting Best Pop Rock album, and get this -- the nominees are Justin Timberlake, Taylor Swift and One Direction. As you know, Kendall was out with Harry Styles this week -- so advantage 1D.

This is Kendall's first time making a big appearance without the Kardashian brood.

I think it went blech, blech, blech ... I think it went grrble, grrble, grrble ...

So, it wasn't exactly the Best Puke Ever ... but Louis Tomlinson from One Direction yacked his face off during a charity soccer match in Europe this weekend ... and it was all caught on tape.

The boy bander had just passed the ball off to a teammate, when Gabriel Agbonlahor -- a really good pro soccer player -- came flying in and knocked Louis on his ass.

Louis rolled around in pain clutching his leg (like soccer players do) ... but eventually got up and made his way to the sidelines.

But as soon as he got off the field, Tomlinson upchucked ... spewing all over the sidelines.

Taylor Swift doesn't just write breakup songs about her ex-boyfriends ... she talks SMACK about them during award shows ... and last night, she got caught. On camera.

It happened when One Direction took the stage to present a Moon Man at the MTV VMAs for Best Pop Video.

FYI -- Taylor used to date Harry Styles (they broke up in January) ... but apparently, she's still harboring some resentment -- 'cause as the band rambled on, the camera cut to Swift ... who leaned over to Selena Gomez and mouthed the words, "SHUT. THE. F**K. UP."

There are people out there who swear Taylor wasn't cussing -- that she was saying the words, "Sorry for my arm."

Those people are stupid.

So ... someone grabbed a feminine hygiene product and fired it at One Direction this weekend, which inspired the following comment from one of our producers:

Rick: "Some girl would rather bleed out than listen to their music."

In their never-ending pursuit of manliness, the guys from One Direction spent Tuesday night on the prowl for tattoos and fried chicken ... and lucky for them, they hit the bloody jackpot in Maryland.

TMZ has learned ... the guys were passing through Glen Burnie, MD this week when they had a sudden urge for some new body art -- so they sent their bodyguard to scope out some of the local needle joints.

We're told the bodyguard liked what he saw when he walked into Tattooed Heart Studios ... and 20 minutes later, in came Liam, Zayn and Louis.

Zayn and Louis each came prepared with some designs in mind -- Zayn wanted an image his of GF's face ... and Louis wanted doodles on his forearm of a spiderweb ('cause he likes Spider-Man) and a bomb ('cause he's da bomb?).

During the session, we're told the guys had a craving for some fried chicken -- so they sent their bodyguard to a nearby KFC, where he picked up a bucket of finger lickin' deliciousness.

The Wanted is out for some boy band blood ... challenging their squeaky-clean pop-nemesis One Direction to a 5-on-5 boxing match (however that works) ... but it's for a good cause.

Max George -- The Wanted's front man and ex-LiLo lover -- told the NY Daily News​ that he and his band mate Jay McGuiness are 100% on board with the idea and not just to bash One D's faces in, but to raise money for charity.

Max told the paper, "We would like a boxing match — them against us. It would be brilliant for TV and I have no problem with it at all.”

Plus, Max says, it would finally settle any beef between the bands -- whose fans often pit them against each other on social media -- explaining, "They’ve got 12 million followers on Twitter and I get that they have an army of kids, but instead of doing that ... if they have got an issue, why don’t we actually do something financially -- like make some money for a charity, and blow off some steam in a boxing ring."

A man impersonating One Direction's Harry Styles was busted Wednesday for making underage girls a deal -- concert tickets for sex.

Authorities say John Eastman gave the girls options -- they could either pose naked or perform sex acts online.

Eastman was arraigned Thursday on a bunch of charges, including employing a minor in an obscene performance.

According to the Waterbury Republican-American Eastman would go online under the Skype name Harry.Styles888 and used photos of Styles to convince the girls he was the One Direction singer.

Authorities say Eastman used his web cam to record the girls performing sex acts and saved them on his computer. Some of the photos recovered feature girls believed to be as young as 5.

It's a miracle Harry Styles is alive ... because the One Direction singer was nearly crushed to death by a mob of screaming chicks in Paris yesterday.

We've said it before ... but seriously, these fan girls are insane -- Harry was leaving Hotel Amour without any decent security, and the screaming female crowd went ABSOLUTELY BANANAS.

The horde nearly swallowed him whole before he got to his car ... no kidding ... he even lost his beanie in the process. It's unbelievable.

She's practically old enough to be his mom ... but that didn't stop Rod Stewart's daughter Kimberly from hopping into a car with Harry Styles last night after a romantic dinner in L.A..

There's been a lot of speculation that 19-year-old Harry has been dating the 33-year-old ... fresh off his breakup from Taylor Swift ... and it's clear from the video, something is definitely going on.

Harry and Kimberly joined Rod and his wife Penny for dinner at Dan Tana's -- and sources inside the restaurant tell TMZ, H&K were flirtatiously fooling around throughout the meal.

There are reports Harry was targeting Rod's 25-year-old daughter Ruby ... but our sources insist Kimberly was DEFINITELY the touchy one. FYI, Kimberly recently had a baby with Benicio Del Toro.

There's a boy band war brewing between Mindless Behavior and One Direction ... and MB has fired the first shot, claiming 1D is second rate because they're LAME DANCERS.

The guys of Mindless Behavior were at Millions of Milkshakes in West Hollywood over the weekend when we asked who's better ... MB or 1D ... and shocker, they said MB.

The reason ... "We can dance."

Taylor Swift and her future ex-boyfriend Harry Styles are making the most of their time together before the breakup -- and hit the slopes for a little ski vacay in Park City, Utah.

The adorable pics were snapped Friday at the Canyons Resort ... when TSwift and the One Direction star decided to take a little lunch break in-between shredding the gnar.

We can't wait to see how this all plays out in a song ... but what rhymes with Utah?

The guys from One Direction hit up a tattoo parlor in Hollywood last night lookin' for some fresh ink ... what they got instead was a straight DISS from the pizza man ... and it was all caught on tape!

A.J McLean has rock-solid proof that the new boy band on the block -- One Direction -- is just a Backstreet Boys knockoff ... because Backstreet Boys wastotally original and definitely not a knockoff.

As we previously reported, the two have been spending a lot of time together lately ... and took a romantic stroll around Central Park earlier this week.

If history repeats itself, "Haylor" will enjoy a few more weeks of dating bliss before things go sour, Swift writes a breakup anthem and moves on to the next unsuspecting hit maker.

Enjoy it while you can, young lovers.

10:00 AM -- Harry and Taylor left the same hotel moments ago, just minutes apart from each other.

With rumors of a secret relationship in full swing, Taylor Swift and One Direction heartthrob Harry Styles were spotted in a FULL-ON CANOODLING SESSION in NYC this weekend.

While there appeared to be no hand-holding or lip-smoochery, the two seemed to be very into each other during a stroll through Central Park.

If ... and only IF ... they dated, Harry would follow in a long line of Taylor's celebrity conquests ... which includes John Mayer, Jake Gyllenhaal, Joe Jonas, Taylor Lautner and Cory Monteith.
