It's not like she can ask Scott Disick to do it!

Kourtney Kardashian braved the rain in LA yesterday to take son Mason to a doctor's appointment, and the reality star was looking mighty skinny in spandex workout pants. It sounds like she's doing everything she can to keep it right and tight for The Biebs!

"Kourtney is getting more and more obsessed with her looks since hooking up with Justin. He’s only 21 and has perfect skin and a flawless fat-free body. Kourtney is working out like never before, making sure she’s super skinny,” a source dished to Hollywood Life.“She also won’t let Justin see her without make up on," the source added.

It's like she's totally forgotten about her estranged baby daddy!

Speaking of The Lord, new reports claim the father-of-three is invited to Kris Jenner's annual Christmas Eve bash, but it's still unclear if he will attend. The whole Kardashian clan opens presents Christmas morning at Kourt's Calabasas mansion, so we bet LD will make that for the sake of his kids.

"This year, we have definitely downsized the party. Because I think the older we get, and with all of us being so busy, it's more important to spend the holidays with our immediate family and really close friends. We always do Christmas morning at Kourt's, and all of our presents are under her tree. We head over in our pajamas when we wake up—it's such a fun tradition!" Kimmy K explained recently on her website.

It would be Kris Jenner's dream if JB joined the celebrations!

Their lives are pretty much identical, so why not dress alike too?

Gigi Hadid and Kendall Jenner got some last minute Christmas shopping done yesterday at Barneys and Trashy Lingerie in LA, and the supermodels wore matching spandex, sneakers, and bomber jackets, which they accessorized with YSL bags. Both of the fashion industry darlings went fresh faced without any makeup on and still managed to look stunning.

The holidays are going to be a bit different for both Victoria's Secret cat walkers this year. Gigi's mother Yolanda is in the process of getting a divorce from David Foster, so rather than opening presents in the family's Malibu mansion, she will more likely be tearing into her gifts from the Dutch model's new high-rise condo.

Kenny, on the other hand, has the whole issue surrounding dad Caitlyn to deal with. We wonder if Cait will score an invite to the annual Christmas bash at Kris Jenner's Calabasas estate? Perhaps the subject is weighing heavily on her mind, because she decided to share a throwback video on Instagram of her father (when he was still Bruce) gifting her with a white pony one Christmas past.

Ahh the life of super rich models with families on reality shows!

it's almost Christmas and I'm just sitting here reminiscing 😌 check out my app to see the whole vid

Yowza!

Khloe Kardashian just unveiled some more super sexy images that were taken during her family vacay in St. Barths months ago, and they're almost hotter than the first ones! The reality star almost flashes nipple as she lays topless in the pool with wet hair and red lipstick. Ow ow!

The impromptu photoshoot happened after a boozy night, and it was none other than her supermodel sis Kendall behind the camera! "We started drinking a little and somehow this impromptu photo shoot turned into a fully nude photo shoot. Even though I've worked really hard on my mind and body to get to this point, I am still shocked I had the courage to do this shoot," she explained on KhloeWithAK.com.

"These pictures are to die for! I cannot believe how unbelievably gorgeous they are! Thank God I have incredibly talented best friends or we could never capture moments like this," she gushed. Assisting on the shoot was her makeup artist Joyce Bonelli and hairstylist Jen Atkin.

In other KoKo news, it appears she has no plans to give up on Lamar Odom anytime soon! "The Lamar situation still weighs on Khloé. She's not one who just walks away. She's going to be there for him, but she also needs to start focusing back on herself – and she knows that," a source dished to People.

Khloe has the biggest heart... and the hottest bod!

A week after losing her children in an ongoing custody battle, Kelly Rutherford appears to be spending the holidays by herself, bopping about Italy. We gotta say -- this seems like a lonely way to spend the holidays.

The former Gossip Girl actress was photographed walking by herself in Milan, Italy on Tuesday. The 47-year-old has been posting Instagram snaps from her lonely looking time abroad. The mother of two posted a snap with some pals on Tuesday night, so it appears she's found a few people to hang out with on her solo trip.

Earlier in the week, the blonde traveled around Florence and posted some photos of things she spied when she was out and about. The actress, who is clearly struggling with losing custody of her children, has also been posting several quotes on her Instagram which have to do with pain and being grateful.

The mother of two received a monthly 3,000-euro stipend for her visits to Europe to see her children since she can't take them back to the States. Rutherford is likely spending Christmas day with her son Hermes, 9, and daughter Helena, 6, who have been living in Monaco and France with their father and Rutherford's ex-husband Daniel Giersch since 2012.

Monaco court's custody agreement says that Rutherford is only allowed to see her kids in Europe and must do so during the second-half of their winter break. After defying the court's orders keeping her children in New York earlier this year, the actress is currently banned from bringing her children back to the U.S.

Sexy ladies Kate Hudson, 36, and Dakota Johnson, 26, appeared to be having a ball on Tuesday night as they swapped their famous mothers for a cute photo op in Aspen, CO.

Hudson dressed casually in a black tank and had her hair up in a ponytail as she sat with Johnson's mom, Melanie Griffith. The 50 Shades of Grey star, who was dressed in a long sleeve tee by Proenza Schouler, wrapped her arms around comedy legend Goldie Hawn.

All four women looked like they were having a ball together, giggling and smiling in the cute snap. The foursome look as if they are hanging out in Griffith's $9 million home that she put on the market last month, following her divorce from Antonio Banderas.

"Goldie, Dakota, Kate and me having some giggles in Aspen! Mother-Daughter times are the best!!!" 58-year-old Griffith wrote when she posted the pic on Instagram on Tuesday.

Johnson looks like has been having a blast on her holiday with her mom, brother Jesse Johnson, half-sister Stella Banderas and some famous friends.

One person who seems to be absent from the pics is Vito Schnabel. Two weeks ago photogs caught Schnabel cozying up to Johnson in a New York bar. It's been rumored that the 29-year-old art dealer left girlfriend Heidi Klum for Johnson.

We know we've been hard on her lately, but this just won her some points in our book!

Caitlyn Jenner fit in some last minute gift shopping in Malibu yesterday, and the transgender reality star was a good sport about posing for a photo with a fan before driving off in her SUV. The Kardashians are notorious for obliging a snap when approached, so it appears Cait is taking pointers from Kimmy K!

We wonder who the I Am Cait star will be spending the holiday with? If you believe the rumors, not Saint West! Allegedly, Kris Jenner will stop at nothing to make sure her ex doesn't get to spend any time with the newborn.

"Kris is the gatekeeper on Kim’s behalf when it comes to appointment times with the baby. She’s in charge of who comes and goes. As far as Kris is concerned Caitlyn has no business being at Kim’s bedside," a source dished to Radar. "Ultimately, Kim’s mom will always come first and Kris has really put her foot down. She does not want Caitlyn cooing over Saint, especially if there are cameras in tow," the source added.

She seems a little lonely and we're actually starting to feel sorry for her!

She’s home for the holidays!

Earlier this morning, Teresa Giudice was released from federal prison after serving nearly a year in Federal Correctional Institution in Danbury, Connecticut. Arriving by a convoy of SUVs, she was greeted by her husband Joe, who begins his own 41-month sentence in March, as well as a reality TV show camera crew and a brand new Lexus, complete with a big red bow.

This morning, the Real Housewives of New Jersey star was met at the prison by her lawyer, James Leonard Jr., who confirmed to People that she was released at 5:01 AM. Teresa is set to serve the remainder of her 15-month term in home confinement. 

The mom of four arrived at home around 7:30 in the morning and was welcomed home with signs that read, “We missed you.”

“She is thrilled that she is finally going home,” a source told People. 'Teresa was smiling when she emerged. She was wearing all black and looked happy.”

It’s beginning to look a lot like Christmas!

If her new fling with Niall Horan hasn't already send Bieber through the roof, Selena Gomez's steamy new "Hands to Myself" music video, which features the scantily clad singer writhing around a bed, most certainly will.

Hubba hubba!

In the music morsel, the 23-year-old plays an obsessed fan who breaks into the object of her affection's home and then walks around in her undies, while fantasizing about some amorous entanglement with the hottie, played by Christopher Mason.

Meanwhile, Selena apparently is out for blood upon hearing the news that the mom of three Kourtney Kardashian has been hooking up with her on-again/off-again boyfriend Justin Bieber. In Touch is reporting that Selena even called up the reality star and tore into her. A source tells the site, “Selena was calling Kourtney a w**re and a s**t." The source added, “When Selena called her, Kourtney asked how she got her number, but all Selena had to say was, ‘I hope you used protection.'”

Burn!

Well at least Selena has Niall and a new song!
