The Kardashians

Kourtney Kardashian's not the only one fed up with Scott Disick -- on the heels of missing his daughter's 3rd birthday, friends are urgently trying to get him into rehab.

Sources tell us Kourtney was peeved about Disick missing Penelope's party at Disneyland on Wednesday, and she was told some of Disick's pals feel it's more evidence he's off the wagon again.

We're told they've been trying to convince him to get treatment -- even before the bday screw up -- and they think they're on a deadline. Scott's scheduled to host a party Friday night at 1Oak in Las Vegas ... which the friends think is a dire mistake.

Our sources say they want him to cancel the appearance and get into a treatment program instead.

Stay tuned ...

When a couple WORKS OUT together -- you know it's serious.

Which is why it was interesting that NBA star James Harden took Khloe Kardashian to a spin class in Hollywood last night ... proving their weekend in Vegas was no fling.

The two hit up Cycle House -- where Harden has hit the bike in the past ... and also happens to be a place featured on an E! reality show called, "Hollywood Cycle."

And with "Keeping up with the Kardashians" also on E! -- seems like the perfect date night, combined with the perfect amount of promotion ... just how the Kardashians like it.

Kourtney Kardashian's wasting no time getting her single chick swagger on -- she got all done up for a night out with her sisters ... the day after cutting Scott Disick loose.

Kourtney was with Khloe and Kim Tuesday evening for a girls night meal at Casa Escobar in Thousand Oaks -- and you KNOW that fishnet dress and midriff-baring top were no coincidence.

Pay attention, Scott -- nothing says, "y'know you done messed up” ... like your ex hitting the town with her hot sisters in a man magnet outfit ... fresh off a body-tightening workout, no less.

Kourtney Kardashian and Scott Disick had their issues -- Scott's partying and substance abuse -- but seeing photos of him with another woman caught her totally by surprise ... TMZ has learned.

According to our sources ... Kourtney had long ago agreed to stick with Scott and work with him as he battled substance abuse problems -- mostly for the sake of their kids.

But we're told infidelity was never an issue between them ... so she was floored by the pics of Scott getting touchy-feely with celebrity stylist Chloe Bartoli in Monte Carlo.

We're told Kourtney also fears Chloe isn't the only girl Scott has cozied up with lately.

As TMZ first reported, Kourtney ended things with Scott after the Monte Carlo incident ... and he hasn't been to their family home in Calabasas in over a month.

Kourtney Kardashian has finally pulled the plug on her relationship with Scott Disick ... kicking her baby daddy to the curb after his partying habits got out of control ... sources tell TMZ.

Our well-placed sources -- and they're solid -- tell us Scott hasn't come home to the family house in Calabasas in over a month and Kourtney lost her patience.

As one source put it, "His partying lately has made her make this tough decision."

We're told Kourtney is also frustrated with Scott's friends -- and believes they're enabling his substance abuse.

Scott and Kourtney have been together since 2006. They have 3 kids together.

It's well-documented that Kourtney and Scott have been rocky over the years -- but we're told, "but now, after 3 kids, it's gotten old and she has to do what's best for the kids."

As for Scott, he was last spotted in Monte Carlo -- getting touchy-feely with celebrity stylist Chloe Bartoli.

Sources tell us Scott knew the relationship had ended -- because he was telling people in Monte Carlo that he was "newly single."

Khloe Kardashian and James Harden couldn't keep their hands off each other in Las Vegas this weekend ... and TMZ Sports has a PIC of the PDA.

Khloe Kardashian's dipping into the hoops pool again -- she and NBA superstar James Harden hit Las Vegas for the 4th and TMZ Sports got the first pics of their date night.

Khloe, James, and his famous beard were spotted leaving dinner Saturday night at Red 8, a fancy Asian restaurant in the Wynn. Vegas sources tell us they looked very couple-y -- snuggling side by side during the meal.

After dinner they went to Drai's Nightclub for Chris Brown's performance.

It's interesting ... Khloe is still legally married to ex-NBA star Lamar Odom, and as we've reported -- there's been zero movement forward in their divorce.

As for how Khloe and the Houston Rockets stud hooked up -- well, Harden was one of the coaches for Kanye West's basketball birthday bash at Staples.

is telling friends she has no doubt ... Scott Disick is hooking up with the chick he was all handsy with in Monte Carlo, but she's also deeply worried he's lapsed and fallen back into substance abuse.

Our sources say Kourtney believes the woman, celebrity stylist Chloe Bartoli, is an opportunist and taking advantage of Scott, whom Kourtney believes is getting wasted again. We're told she knows Chloe and, as we reported, Scott knows her as well ... they even dated.

Our sources say Kourtney's sisters have the same view as her and on Friday they all went from simmer to boil, targeting their anger at both Scott and Chloe.

Poor Scottie Pippen ... all he wanted to do was hit the clubs with his friend Kourtney Kardashian this weekend -- instead, she shot him down.

Kourtney and Scottie were each having dinner with friends at Craig's in West Hollywood (Scottie was with Ron Harper) ... but on the way out, Pippen decided he wanted to crash the party scene.

So, he goes to Kourtney's SUV -- convinces her to roll down the window and asks KK if she wanted to hit up 1 OAK on the Sunset Strip ... after all, Kourtney is friends with Scottie's wife, Larsa!

But alas, Pippen got rejected ... because Kourtney ... well, she had other plans. Super boring other plans.

Kris Jenner took her man Corey Gamble to the Palace of Versailles in France over the weekend ... and no doubt regaled him with tales of the Kim Kardashian/Kanye West wedding.

Kris has the most epic Versailles photos ever, but she and Corey still snapped a few selfies as they walked among the common folk.

Kim Kardashian is calling BS on a story told by the wives of the 2 men who inspired the ALS Ice Bucket Challenge -- claiming she was being uncaring and snobby.

Eyewitnesses who were with Kim tell TMZ ... Kim insists the incident, which one of the women chronicled on Facebook, did not go down the way they said.

The women claim they saw Kim and Kris Jenner in Celine -- a fancy schmancy women's store -- and asked for a pic with Kim, after explaining who they were. They say when they told Kris their husbands had ALS, Kris fliply responded, "Oh fun," and Kim and Kris blew the women off by refusing a photo.

But we're told a group of women hounded Kim and some even knocked on her dressing room while she was naked. Sources say when Kim came out Kris was talking to a couple of ladies and they told her they were in Cannes and were having a great time shopping and going to parties, and that's when Kris replied, "Oh fun."

As for denying a pic, the eyewitnesses claim neither of the women asked Kim for a photo when she walked out of the dressing room. She simply exited and smiled for all the cameras pointed in her direction.

Our sources say, Kim and her mom obviously support the cause ... as you know Kim famously did the challenge on TV, and if Kim knew the women were even there, she would have loved to sit down with them and talk about how she could help.

Kim Kardashian got an early morning wake-up call -- not from her French hotel's front desk -- but from a random drunk woman banging on her door!

According to our sources ... pregnant and hormonal Kim was rousted out of bed at 4 AM when the woman started kicking her Cannes hotel room door, and trying to get in for a tête-à-tête. Kim went to check who was banging, and got treated to a view of the woman lifting up her dress and flashing her.

We're told Kim yelled at the woman to beat it, but she refused to leave -- and Kim had to call security 3 times before they arrived to gave la chick ... le heave-ho.

Caitlyn Jenner didn’t unwrap any ties this Father’s Day … she finally got the gifts she’s always wanted – dresses and a day spent as a woman of leisure.

As we previously reported, several of Caitlyn’s kids joined her at her Malibu pad on Sunday, and they didn't come empty-handed.

We’re told the Kardashian girls went all out gifting her with dresses, shoes and accessories for her new wardrobe. Her elder sons Brandon and Burt did yard work so that Caitlyn wouldn’t have to get her manicured hands dirty.

It’s a breaking of tradition for Caitlyn and her kids, who in years past always resorted to sports-related Father’s Day gifts or the token tie.

We're told Caitlyn felt it was the best Father's Day ever.

Caitlyn Jenner had almost a full crew of kids dune buggying all over Malibu for Father's Day, and the pic is kind of awesome.

Kim and Kanye were front and center with North West, along with Khloe, Kendall, Brandon and his wife, and Burt and his girlfriend, Valerie.

We're told Kourtney had the flu and Brody was out of town on a DJ gig.

As we reported, Caitlyn threw the party and it's one of the few times her kids from different marriages showed up.

It's the first time we've seen Caitlyn out in a dress. She looks great, but maybe a tad overdressed for off-roading in a Polaris Buggy.

Caitlyn Jenner is under criminal investigation for her fatal car crash in February, and we've learned prosecutors are putting Jenner under a special microscope ... a microscope normally reserved for murderers, kidnappers and extortionists.

Law enforcement sources tell TMZ ... the L.A. County Sheriff's Dept. is a couple of weeks away from completing its investigation. The Sheriff would then normally send the case to the D.A.'s closest satellite, which in this case is Van Nuys.

But law enforcement tells us the D.A. has quietly told the Sheriff that the case will be sent to the big guns at the main office in Downtown L.A. ... in the Major Crimes Unit.

The Major Crimes Unit deals almost exclusively with extremely serious felonies. Think of the way the Navy SEALs are to the Navy. But Major Crimes will be reviewing Jenner's case, and one law enforcement source connected with the case calls it "surprising."

Law enforcement sources familiar with the case feel Jenner should not be charged with a crime at all ... Jenner wasn't texting or on the phone ... it was momentary inattentiveness that ended badly. But the sources say even if Jenner gets charged, it would certainly be a misdemeanor, not a felony.

Although the D.A. wants Major Crimes to make the final decision, it will never be filed as a felony. In the greater scheme, it's a petty case.

Fact is ... a lot of cases involving celebs end up in major crimes because they're high profile.

North West is gonna have a little brother to taunt, because Kim Kardashian just spilled the beans.

Kim chose the appropriate day for the reveal on social media, saying to Kanye, "Precious moments like this when we were traveling on tour with you and what I live for," adding, "You're such a good daddy to North & you will be the best daddy to our new son too!"

We had heard it was a boy for a few weeks, but Kim chose to make it official late on Father's Day.
