Kim Kardashian and Kanye West threw their daughter North an extravagant birthday party yesterday at Kourtney's Calabasas home, and from the ferris wheel to the stage, they really went big!

The bash was inspired by Coachella (they called it "Kidchella"), and the Kardashians asked that guests dress like they would at the annual California music festival. Khloe went all out with a Native American headdress while Kendall and Kylie wore shorts tops that probably didn't make the cut this year when they packed for the party in the desert.

Kendall and Kylie spent quite a bit of time lip-syncing songs on the mini-stage (mom Kris Jenner posted videos of them rocking out to Rihanna's "We Found Love" and Kanye West's "Good Life"), and there as also a big bounce house and food stands.

"Kim was holding North a lot of the time, and the party seemed to be geared towards a little bit older kids," an eyewitness tells Us Weekly. "But it was a family party with all ages, and no matter what age they were, they were having a great time. There was so much to do." We're not sure who planned this, but it does look pretty awesome!

Khloe posted the photo of herself above with the teepee and wrote, "Ray of clouds. Chirping of birds. Gurgling of water. Granting desire. One with water. #Kidchella, my first Coachella!!!" Check out the gallery below for more photos!

Jessica Simpson obviously believes the old mantra, "If you've got it, flaunt it!" because girlfriend is showin' if OFF!

The sexy two-time mom and fiance Eric Johnson left celeb hotspot Fogo de Chao in West Hollywood after a yummy meal celebrating Jess' BFF Cacee Cobb's hubby Donald Faison's 40th birthday.

But all eyes were on Jessica as she strutted out of the restaurant in her 6-inch platform heels and sexy, silk floral romper. Eric held on tight, ensuring Jess didn't take a tumble in her sky-high heels.

Simpson's hair was impeccable, her lips freshly-glossed and Eric was looking ... well, happy. He's about to marry a multimillionaire singer with the most successful celebrity clothing line empire ever; he's got two adorable kids and a his rich fiancee is super hot!!! Life is good!

It was a casual Friday for Kendra Wilkinson as she sported a hoodie and some sweats while on her way to the doctor's office in Beverly Hills. Did we mention she was also make up free?!

The 29-year-old appeared to be in good spirits despite reports that her husband Hank Baskett abruptly left their Calabasas home that day.

According to the National Enquirer, the former NFL star reportedly was seen speeding away from their gated community and arriving at a local motel yesterday afternoon.

This development comes only a month after the married couple welcomed their second child, Alijah Mary Baskett.

Hope this isn't a prelude to something else!

Wow she looks great!

Jessica Simpson showed that she's still got it as the Weight Watchers spokesperson posted a picture of herself on Instagram yesterday with friend Stephanie Terblanche looking lovely in her little black dress.

The 33-year-old mother of two appears to have clearly reached her ideal wedding weight and with her pending nuptials inching closer, it's great to see that her hard work has indeed paid off!

Not in that way!

Kevin Federline let it all hang out as he sported a Go Commando t-shirt while with his wife Victoria Prince and their daughter Peyton Marie at Starbucks on Friday.

Britney Spears' ex clearly enjoys fatherhood as his total tally of children has hit the magic number of six.

Wonder if he'll go for lucky number seven?!

Is he sleepwalking?!

Early this morning, it appeared as if Kanye West hasn't gotten much rest lately as he looked to be still sleeping while walking through New York's JFK airport.

The 37-year-old rapper has had quite the whirlwind schedule recently, having been to Cannes, Paris, Miami and the Big Apple now in the past few days, not to mention any parties and daddy duties. Talk about your frequent flier miles!

Though he wasn't spotted with Kim Kardashian or his baby girl, we suggest he get some rest!

Looks like retail therapy CAN cure everything!

Yesterday, Chris Brown and Karrueche Tran took a trip to do some shopping at the Beverly Center in Los Angeles. Isn't that cute?!

The 25-year-old embattled singer and his girl seemed to have rekindled their flame as things have gotten better for their relationship since he was released from jail on June 2. They even hit up Hooray Henry's together later that night!

This must be love!

Justin Bieber and Selena Gomez are officially back together!

We spotted the pair out on a romantic dinner date last night at Mastro's steakhouse in Beverly Hills, arriving together in Bieber's van around 8pm and staying for a leisurely 2-hour meal!

A source inside the restaurant tells X17online the two were ensconced in a corner table, in the back room, where they sat close to each other, holding hands, nuzzling, talking and laughing: "Justin stared into Selena's eyes and gave her his full attention. He didn't have his phone out or anything -- it was like everything else disappeared and all he cared about was her."

After steak and potatoes and a hearty dessert, Justin and Selena headed out through the kitchen, out the restaurant's back door, to Biebs' waiting van and they were off to see a movie. Other than the $400 dinner bill and the chauffeured car, just your average date night!
