Kourtney Kardashian had a serious mom moment -- she looked away for a split second, and one of her kids took a car door to the face!

Kourt was actually holding 3-year-old Penelope's hand as they walked past a parked car in Malibu on Sunday -- and at that very moment, one of the car doors flung open.

Poor Penelope went down in a heap, and, naturally burst into tears. Mom and the nanny quickly comforted her ... and we're told she's okay.

Justin Bieber's lawyers are barking about three nude pics taken of him on vacation in Bora Bora, but we know Justin isn't all that pissed because the shots show just how ... GIFTED he is.

Multiple sources close to Bieber tell TMZ he was upset paparazzi, armed with telephoto lenses, snapped the photos of him butt (and other parts) naked frolicking with Jayde Pierce. We're told he thought it was a total invasion of his privacy.

We saw it the same way, and decided NOT to post the images. But our sources say Justin's anger faded when the pics went viral ... for one seemingly larger than average reason: Bieber's a really big deal, and we're told he's happy the world knows it now.

As we reported, JB's lawyers threatened media outlets that published the pics. We're told his legal team was just doing its job ... sending the message that Justin's not okay with the violation.

But reality is, there's almost zero chance Justin sues ... 'cause as they say, size matters.

Marilyn Manson was on the hunt for Dr. Claw as he left Nice Guy Thursday night in West Hollywood.

Go go gadget!

And if that doesn't work out, maybe Jared Leto might need a stand-in for "Suicide Squad."

Just sayin'.

Bella Thorne was bound to have a blast on her 18th birthday -- and so was her chest.

Bella showed up at Beso Restaurant in Hollywood ... sporting leather (mini-skirt) and a laced up top ... to celebrate adulthood with friends.

Her 23-year-old BF Gregg Sulkin was also there, because while it was Bella's big night ... it was even bigger for him. Just guessin'.

Ain't always pretty, but Jared Leto wears whatever the hell he wants, and it looks good ... on him. Usually.

Leto was cruising around NYC, still sporting a pink 'do ... which we're guessing is left over from shooting "Suicide Squad."

Based on the multi-colored pants and poncho, someone might have raided the wardrobe trailer.

Justin Bieber and his team are sending a strong message -- the nude photos of him published this week invaded his privacy, and anyone who posted them should take them down immediately.

TMZ has confirmed Bieber's legal team has sent multiple cease and desist letters to news outlets that published the pics, saying remove 'em or else. They claim the photos were taken without Bieber's knowledge. They show a naked Bieber in Bora Bora ... right before jumping into a pool.

Liam Hemsworth is catching waves instead of fire.

"The Hunger Games" star hit the water in Australia Wednesday for a surf session.

Looks like the youngest of the Hemsworth brood can hang ten ... even in the stomach department.

Anchor? Benzino barely knows her!

Okay, he actually does know her ... but we couldn't resist after seeing Benzino's maritime-themed pose with GF Althea Eaton's ever expanding uterus.

The former "Love and Hip Hop: Atlanta" stars announced in July they're expecting their first child together.

We know this much ... the kid's gonna be a fighter.

Tom Hanks is a dead ringer for Captain Chesley "Sully" Sullenberger, right down to the mustache, walking down a NYC sidewalk.

Hanks is in the Big Apple filming the biopic on the retired US Airways pilot who miracuously crash landed on the Hudson ... killing no one. Clint Eastwood is directing.

Good things happen when Hanks plays captain -- in WWII, on hijacked tankers or on shrimp boats.

Brace for Oscar impact ...

Here's what Cindy Crawford really looks like untouched ... in a bikini.

Crawford hit the waves Monday with husband Rande Gerber in Miami, putting body shaming Internet trolls in their place with her itsy bitsy white snakeskin bikini and flat torso.

It's sweet justice for the mother of two who became the victim of an unflattering Photoshop prank.

Gerber seems to be keeping up with his wife, for the most part.

She turns 50 in February. Life truly is unfair.

Caitlyn Jenner and daughter Kylie grabbed lunch Monday ... the first time they've been seen in public since Kylie's 18th birthday party.

The two nibbled on sushi at Sugarfish in Calabasas after attending a NOH8 event in LA.

They were matching right down to the lipstick. Caitlyn opted for a more neutral color, while Kylie wore blue to show her support in honor of world bullying day.

Matthew McConaughey won't be donning prosthetics for his new movie "Gold" to turn himself into a Mr. Burns look-alike.

Oscar winners always go the extra mile.

Zoe Kravitz stacks up just fine against "Are You Gonna Go My Way" ... "Always on the Run" ... "Fly Away" or "Let Love Rule."

The "Dope" star was hanging on South Beach in a little black bikini -- reminding us Lenny Kravitz and Lisa Bonet's music, movies and TV shows are NOT their only legacy in entertainment. Definitely not their hottest either.

American woman ... please come knocking around our door.

This is the ultimate power lunch -- a table for three with the guy who co-created Def Jam, the guy who directed "Iron Man" and the guy trying to colonize Mars.

Elon Musk, Jon Favreau and Rick Rubin all met for lunch Sunday on the Malibu Pier.

Favreau has mentioned his friendship with the SpaceX and Tesla Motors CEO in the past, saying he based "Iron Man's" Tony Stark on Musk. No word on how they both know Rubin, but there is a Def Jam film in the works.

Just how powerful was this meal? Check their reported net worth stats: Rubin, $250 Million ... Favreau, $60 Million ... and Elon Musk, $13.2 BILLION!

Photos from the DUI wreck Brandon Davis had Thursday night show just how horrific the accident was -- and TMZ has learned he was hanging with former NHL star Mike Comrie beforehand.

We broke the story, Brandon -- heir to the Davis oil fortune -- had a single car wreck in L.A. and absolutely destroyed his Mercedes Benz sedan. Davis was transported to a hospital, where police arrested him for an alleged DUI.

Earlier in the evening, Brandon was seen drinking wine with Comrie -- Hilary Duff's estranged husband -- at L.A. sushi joint Matsuhisa. It doesn't appear Comrie was in the car with Brandon at the time of the accident ... as the ambulance only transported one patient.

Davis, aka Greasy Bear ... has been released from the hospital, and is getting transported to jail.

'80s icon Grace Jones might be a senior citizen, but she's still pushing book sales like she's 25 -- Buy my book, see my boobs!

The ex-model and singer flashed fans and photogs who showed up at her NYC book signing Thursday -- walking the walk after she smack talked Miley Cyrus, Nicki Minaj, Rihanna and several other celebs.

67-year-old Grace thinks the new generation doesn't "challenge the status quo" enough. Hear that ladies? Get yer protest ya-yas out!

Still Strangé after all these years ...
