A hot and sweaty Justin Bieber always makes us hot and sweaty! Somehow, though, Bieber prodigy Madison Beer kept her cool as she "hiked" with the world's sexiest pop star. Beer didn't realize how seriously Biebs takes his hikes -- he trail runs but she wasn't prepared in her fringed Converse high tops and Chanel backpack.

Justin didn't care, though -- he ran ahead, keeping a pretty fast pace. When we asked Madison if she has trouble keeping up, she concurred! And by the way ... could these two be hooking up???

Lamar Odom has checked into a rehabilitation facility near San Diego, Calif., according to E! News. The troubled former NBA star didn't fall off the wagon, according to the report, he just went in for a tune-up, E!'s source says: "It was his own decision. He wanted to work on his mental and physical health for the next chapter of his life. He has not fallen off the wagon, but he understands the importance of maintaining his sobriety."

Odom overdosed in a Nevada brothel in October 2015, which sent him into a coma and into a long recovery phase once he came-to. Of course Khloe Kardashian was by his side every step of the way but, as the family's reality show Keeping Up With the Kardashians has documented, Khloe has been ready to be cut loose from her responsibilities to Lamar for a while now. She wants to move on with her own life and find a man ... and she's certainly done that!

X17online got the EXCLUSIVE photos of Khloe and boyfriend Tristan Thompson as they touched down in LA early Sunday morning for a romantic weekend in Khloe's hometown. In fact, the two were probably celebrating Khloe being in the last phase of her divorce proceedings with Lamar.

Could the reality of losing Khloe have sent Lamar over the edge and seeking support???

Things are heating up between Khloe Kardashian and boyfriend Tristan Thompson!

The denim-darling, 32, brought her baller boyfriend, 25, back to LA after the Cleveland Cavaliers played on Sunday. The sneaked in, during the dark of night -- at midnight -- by private jet. The kept their rendezvous on the down-low, staying away from the usual dinner and club hotspots in favor of a weekend at Khloe's Calabasas mansion.

What they DID do Sunday night was to pop over to Kris Jenner's house for dinner. Of course it's not the first time Tristan's met the family matriarch, but we're told as the young couple's relationship heats up, Tristan is increasingly concerned -- as is Khloe -- with mama Kris being on board with their relationship. Our source tells us: "Khloe's paving the way for Tristan to ask for her hand in marriage. She wants him to feel comfortable around Kris so he can propose when he's ready -- she knows it's coming."

Oh lord, another baller hubby!

Congrats are in order!

Erin Andrews was flaunting a pretty serious diamond ring when she landed at LAX today, and the sports commentator was so giddy she couldn't help but confirm her engagement to NHL star Jarret Stoll.

Her former Dancing with the Stars partner Maksim Chmerkovskiy let the happy news slip last Friday during an interview with Fox 5 in Las Vegas, when he said the blonde beauty "maybe just got engaged."

The couple began dating in 2012 but temporarily split in 2015, when the athlete was arrested on suspicion of cocaine and ecstasy possession.

Watch the video to hear how her man popped the question!

She's such a tease!

Kylie Jenner has once again shared some behind-the-scenes images from her racy 2017 calendar photoshoot.

On Monday, the teen posted some snaps from her upcoming raunchy calendar on her website. In one of the pictures, shot by controversial photographer Terry Richardson, show the teen in white wig, wearing white lingerie and sucking on a red lollipop. Another snap showcases Kylie wearing a gold bathing suit and flexing her muscles.

Last week the reality star posted some other images in which the blonde displayed her bootylicious body with a python wrapped around her.

For all you King Kylie fans who don't care that she's posing for a man who's been accused several times of inappropriate conduct by many models, you can put your hands on this racy calendar, which was available on Dec. 10!

Talk about hot travel buddies!

Bella Hadid, Hailey Baldwin, Emily Ratajkowski and a bunch of other models are currently frolicking around the Bahamas in bikinis, and while we think it's for a photo shoot, it's very possible they're all just friends and wanted to head somewhere tropical to relax. How smokin' do Bella and Em look on that jet ski?!

We bet the group had no shortage of topics to discuss. Gigi Hadid's little sister recently broke up with The Weeknd, and ol' Hails is rumored to be still secretly hooking up with The Biebs.

On another note, we're seriously wondering how all these babes have such good bods? If you follow any of them on Snapchat, you would know that all they seemingly do all day is eat cheeseburgers. That can't be the case!

Rehab does a body and (bank account) good!

Fresh off her stint in rehab, Selena Gomez has just signed a $10 million deal with Coach to become the face of the brand. The popstar will also be designing her own line of luxury accessories, reports Page Six,

This has been a big year for the one for "The Heart What It Wants" singer -- she did three months in a rehab facility in Tennessee, won Favorite Female Pop/Rock Artist at the American Music Awards on November 20 and she also just emerged as the most popular person on Instagram for the second year in a row with a whopping 104 million followers.

We have to say having the top celeb spot on Insta is pretty impressive because the brunette didn't post for the three months she was seeking treatment and she hasn't posted anything in the last two weeks.

It's pretty clear, no matter what, the people love Selena, and we have a feeling they will love her Coach bags!

I love you @beyonce thank you sooooo much for coming out tonight! ❤️😘🎤🙌🏽💋#merrychristmas

We would have assumed they hated each other!

Beyonce attended Mariah Carey's All I Want for Christmas Is You concert in NYC on Sunday night, and Mimi couldn't help but heap praise on her pal via social media. “I love you @beyonce thank you sooooo much for coming out tonight! ❤️😘🎤🙌🏽💋#merrychristmas," she captioned a photo of the pair.

Given the Mariah's World star's massive beef with J.Lo, we're pretty surprised she's so cool with Bey. We must have missed her gushing about the "Lemonade" songstress on Watch What Happens Live! back in May.

"I love Beyoncé. She knows this, most people know that. I'm a fan, I love her and we have fun together, like she's a fun person, she's really cool. I would love to do a collaboration with her," she told Andy Cohen.

That's a whole lotta ego for one friendship!
