The Kardashians

Lamar Odom checked himself into rehab out of fear he'd go on a major bender as his deceased son's birthday approached ... TMZ Sports has learned.

Lamar's son, Jayden, was born Dec 15, 2005, but died the following June from SIDS. We're told his son's death was the primary reason he started doing hardcore drugs ... and he was keenly aware the birthday might push him over the edge again.

As we reported, our Lamar sources say he went to a San Diego area facility late last week.

We're told Lamar's also struggling with the fact his divorce from Khloe will be final on Saturday, and he didn't want to be tempted to use.

Lamar is shooting for a 60 day rehab stint. He bailed after 3 weeks when he attempted rehab in 2012.

Kylie Jenner's putting one of her empty cribs to good use -- we're told she's renting it out to Rob and Blac Chyna.

The new mom and pop moved into the Hidden Hills, CA home this week, and the reason's simple -- Rob and Blac wanted a bigger pad, and to be closer to Kris and Kim's nearby homes with baby Dream now in the picture.

As TMZ reported, BC's house in Tarzana was supposed to be home base once Dream arrived. But that plan's changed, and we're told Rob's still working out leasing terms with his little sis.

This is the same 6 bedroom, 7 bath spread where Chyna recently posed with King Cairo ... Christmas lights and all.

Khloe Kardashian's ass isn't hard to find ... unless you're GQ Germany, which didn't highlight her greatest asset in their photo shoot with her.

Luckily, we found this footage of her butt front and center here, from behind the scenes of that GQ shoot ... in all its glory.

Scott Disick just can't escape his baby mama's family -- he's struggling to unload a Kardashian-adjacent home, and just slashed its price ... by a lot of zeroes.

The Hidden Hills pad Scott bought a year ago, and listed 6 months later at $8.8 mil ... is now $1 million cheaper. Don't cry for the lord, he could still make a little less than $2 mil on the deal.

You'll recall ... he bought the 7 bed, 6 1/2 bath house for a steal at $6 million to be closer to Kourtney and the kids. Since then, he's made renovations, but hasn't gotten a bite yet.

Kanye West's recovery is giving him time to refocus on his true work of art -- the former mansion he and Kim are expanding into a mini-Versailles of the Valley.

Sources close to Kanye tells us he's been working closely over the last week with contractors at the Hidden Hills, CA pad. The most recent project was expanding the master bedroom.

We're told 'Ye blew out an entire wall to add on a space that looks way bigger than the average NYC apartment -- and he's not done yet.

We reported ... Kanye's currently making new music from a temporary studio in their Bel-Air home -- and we're told the new mega mansion is being prepped for installation of a fully equipped music lab.

As for the decor -- we know Yeezy's fond of Rick Owens' furniture, and you'll recall it was one of Rick's exhibits that drew him out in public this week. We're told there's a good chance 'Ye was window shopping for his huge new space.

Charlamagne Tha God is down to talk about our Prez elect or Russians hacking emails -- but bring up Kim Kardashian ... and it's gonna get ugly fast.

The 'Breakfast Club' co-host was leaving Warwick in Hollywood Saturday night when our photog launched a political convo, and it was clear Charlamagne has strong opinions about Donald Trump.

The only thing he's more pissed about is our guy trying to pivot to Blac Chyna's feud with the K sisters. Wrong move.

Charlamagne is so passionate in this clip, we gotta give him this side-by-side shot. Watch, he'll explain.

Kylie Jenner played dress up by putting on much LESS clothing, and it was all for Christina Aguilera. Sorry, Tyga.

KJ made an encore appearance in her Xtina costume at Aguilera's 36th birthday party Saturday night. Kylie dressed like Christina from her "Dirrty" days of 2002 ... just like she did for Halloween.

Normally, it's a serious faux pas to repeat a costume, but Kylie says Christina made a special request. Plus, they kissed on camera.

No tongue, but we're still good. She should wear this every night, actually.

Kylie Jenner's maternal instinct might start to kick in early -- it's the first time we've seen her hold Dream Kardashian -- and she's doin' it like a pro.

Kylie posted the vid Saturday with her newest niece, and while it's unclear whether Rob or Chyna (or both) gave her the green-light ... both Kylie and baby seem pretty content.

Kim, Khloe and Kourtney Kardashian are sticking to their guns when it comes to stopping Blac Chyna from the family name -- and neither marriage nor their mom will change that.

Sources close to the sisters tell us they will not withdraw their opposition to Chyna's application to trademark "Angela Renee Kardashian" -- despite Chyna's side saying there's no legal war brewing.

As we told you, BC sources say Kris Jenner reached out and promised to call off the lawyers. But our K sis sources say that's not how they feel about it. We're told it's nothing personal against BC, just biz -- they feel adding an extra woman to the roster will dilute the brand they've worked so hard to build.

We're told they think it's odd Chyna didn't move for a trademark when she was with Tyga -- although that's kinda apples and oranges. $1 if you know his last name.

Our sources close to Kris say the conversation those close to Chyna alleged the two had to smooth things over never even took place.

On a personal level, we're told everyone in the fam is getting along well with Chyna since the birth of Dream. Still, business is business and our sources say the sisters' lawyers have made several attempts to negotiate ... but Chyna's team's gone radio silent.

Blac Chyna got railroaded by the Kardashians' attorneys -- not the K sisters themselves -- in her effort to trademark herself as a member of the fam ... and now Kris Jenner's doing damage control.

Sources close to BC tell TMZ ... Kim, Kourtney, and Khloe reached out to her and assured her their lawyers were following standard ops when they filed docs to block Chyna's application to trademark "Angela Renee Kardashian" -- not singling her out.

The assurances were necessary after the language the lawyers used. We broke the story ... the docs said all 3 sisters would "suffer damage including irreparable injury to their reputation and goodwill" if Chyna got the green light to use the Kardashian name in entertainment.

We're told Kris personally told Chyna there's no beef ... it was a simple mix-up and she's calling off the legal eagles. For now, everyone's saying the right things to make Chyna feel better about the legal diss -- but, fact is, her trademark still hasn't been approved.

Khloe Kardashian just launched the sexiest blitzkrieg in history.

Khloe slipped into some "schtuppe mich" boots for the latest issue of GQ Germany. She wore a bunch of other outfits too, but with much less material.

The photos are hot, for sure, but they missed one big thing -- her ass. She even got upstaged for the issue's cover.

Just because Blac Chyna's marrying a Kardashian doesn't mean she can get in the club -- the Kardashian sisters are going to war to block her from cashing in on the family name.

According to docs obtained by TMZ ... Kim, Khloe, and Kourtney's companies are opposing Chyna's request to trademark "Angela Renee Kardashian" -- which she was trying to lock down for use while working in entertainment, and also on social media.

The mean girls sisters throw down the gauntlet in docs, saying if Chyna gets the trademark they'll "suffer damage including irreparable injury to their reputation and goodwill."

Translation: stay in your ex-stripper lane ... you're not one of us.

Make no mistake ... this is nasty. In the docs, they say Chyna is "deliberately seeking to profit from the goodwill and popularity" of the Kardashian name.

Rob Kardashian and Blac Chyna are all in when it comes to cashing in on their milestones as a couple ... and they're ready to start talking turkey for a TV wedding special.

Sources close to the couple tell TMZ ... they're on solid ground since Dream's birth, and want to get married next year. We're told there's no date set, but one major factor in that decision will be what's best for TV.

There's nothing contractually obligating them to shoot their wedding, but for the right price ... they'd be all about it. Remember, they scored a sweet deal for their baby birth special which airs in a couple weeks.

Our sources say Rob and Blac already have a few venues in mind, but they're not locking anything down just yet. As for Dream, there's no drama in the co-parenting dept and she's helping them grow closer.

Now an agent just needs to get 'em closer to a TV deal.

Kylie Jenner has planted temporary roots in Miami ... and the pad she's calling home looks like it could double as a space station.

Sources close to Jenner say the $15 million, 6 bedroom 7 bathroom mansion is currently occupied by Kylie, Tyga and friends while they hang out for Art Basel. Not only does the place have a rooftop balcony ... it's got a lap pool, futuristic design and is right on the water.

Jenner's been flaunting the crib's elevator during her trip, and if you wanna take a ride ... it can be done for a whopping $8k a night on Airbnb.

Sure beats the local motel.

Kourtney Kardashian and Scott Disick are together, just not ALL the way together -- nudge nudge, wink wink -- TMZ has learned.

We're told Kourtney and Scott are on better terms than they've been in years -- he's staying clean, and has been a present father -- but she still isn't sold enough to make a romantic leap.

Rumors that Scott's already won her back just aren't true, according to our sources ... who say Kourt insists there's no intimacy. We're told Scott still stays at his own house, and although they often travel together ... it's purely for co-parenting.

But as for the future -- she's open to the idea of an encore from the Lord.

Kanye West will be recovering in the yuletide spirit -- it's full steam ahead on Kardashian-sized holiday decorations at his house, days after leaving UCLA Medical Center.

It took at least half a dozen workers to squeeze a giant Christmas tree -- looks to be at least 25 feet tall -- through the doors of Kim and Kanye's Bel-Air home.

There was also a huge water delivery. As we previously reported, 'Ye's doc told cops the rapper's temporary psychosis was brought on by sleep deprivation and extreme dehydration ... although we've since learned Kanye's issues run much deeper than that.
