Kris Jenner seemed to be in a bright mood on Friday night when she touched down at LAX.

Earlier in the week, the 57-year-old businesswoman came under fire for allegations of abuse after In Touch reported that they have obtained diary entries from the late Robert Kardashian that described Jenner physically abusing her daughters.

While Jenner has refuted the claims, Kim Kardashian went on a mini tirade on Twitter to defend her mom amid the false allegations.

"So my dad's ex is selling ridiculous stories again to tabloids! Do not believe it! Sad when people need $ & get desperate," she tweeted on Thursday. "10 yrs since dad passed &this woman he married 4 2 wks before he died needs 2 get a job instead of trying 2 destroy families w fake stories. PS that story that my mom beat me & threatened to kill me hahahhahaha! I'd beat her! JK truly laughable! #NOTTRUE."

Earlier this week, In Touch kicked off a frenzy of media reports by publishing a story detailing the Kardashian girl's unstable upbringing. Kim, Khloe, and Kourtney's lawyer father Robert Kardashian apparently documented all of the mental and physical abuse by his former wife in a secret journal, which the family believes was given to the magazine by his widow Ellen Kardashian.

One journal entry details how the family matriarch kicked and threatened to kill Kim when she was just 8-years-old. Another claims that the momager used to abandon her kids to have sex with her boy toy lover Todd Waterman during her extramarital affair, and wouldn't even call to check-in on them for days at a time.

Apparently the Keeping Up with the Kardashian stars still carry the scars from their rocky relationship with their mother, which is why more often than not, they refer to her as Kris, rather than mom.

Although it is pretty difficult to deny things when cold hard evidence exists, the reality stars are fighting back and slamming their stepmom for selling "lies" to the media for money.

"You should be hiding in shame for all of the lies you sell to tabloids!! 10yrs after my father's passing & now that she has filed for bankruptcy... NOW she sells FALSE stories. Hope that money buys you water in hell," Khloe furiously tweeted.

Although Kris has yet to speak out on the story, the family rep denies all the allegations. "We have no knowledge of these diaries existing and these accusations are ridiculous and not true," the rep said in a statement.

On Friday night Kris Jenner attended the Lakers/Clippers game at the Staples Center in Los Angeles, and not only did she look thrilled to see son-in-law Lamar Odom beat his former teammates, but she also chatted with us about Kim's pregnancy!

So what did the reality star/momager have to say about her 3rd grandchild? Click the video below!

Happy birthday, little guy!

On Friday, Kim, Khloe and Kourtney Kardashian got together to help celebrate her son Mason's third birthday in Miami. He's a growing boy!

Kourtney's baby girl Penelope, along with Scott Disick, joined in on the festivities as the family first went to Gold Coast Railroad Museum before dining at Serendipity afterwards. We bet he just loved all the attention!

Over the weekend Kris Jenner tweeted this photo of her Halloween costume, but after realizing that she accidentally included a peek at her nipple, she deleted the shot. Of course, Khloe didn't want to let her forget, as she re-tweeted the shot and added, "Hi nips. That's my mom."

Looks like Kim's gonna have to step it up to compete with her mother!

Just another day in the life for the Kardashian clan!

Kim Kardashian caught a flight out of Miami today, and the reality star doesn't seem to know the meaning of travel style! The brunette bombshell rocked Louboutin pumps and leather pants for her day in the skies, which isn't exactly the most comfortable outfit!

Meanwhile, her momager Kris Jenner was back in LA shopping at Trashy Lingerie. Let's hope the 56-year-old was there to buy gifts, not shopping for a Halloween costume for herself! Just like Kimmy K needs to learn the term "travel style", Mrs. Jenner needs to learn the term "age appropriate!"

Just last night, the E! matriarch took in the Justin Bieber concert with her famous daughters, and she opted to wear leather pants and a see-thru leopard top!

Now we know where the K ladies draw their skimpy style inspirations!

For the second night in a row, Kris Jenner took her daughters to the Justin Bieber concert at the Staples Center in Los Angeles, and the ladies dressed to the nines for his show.

Kendall exposed her midriff and wore a pair of skintight jeans, and while Khloe kept her outfit on the casual side, Kris gave her teenage daughter a run for her money with a pair of leather pants and a wild animal print blouse. While the clothes aren't exactly age appropriate, we can't hate -- she def doesn't look 56 years old!

Kim and Kris Kardashian, along with pal Jonathan Cheban faced off against Bruce, Kylie and Kendall Jenner and Kourtney Kardashian in Miami's Dragon Boat Festival race, on Saturday.

"Going for the gold," Kylie Jenner Tweeted early yesterday morning. Kim followed up with: "Ready to row #teamDASH."

So who came out on top? Team Jenner took top prize ... not much of a surprise -- after all, Bruce IS an Olympic gold medal winner!
