It looks like yesterday was filled with children's birthday parties galore.

Kourtney Kardashian took her kids to a party in Beverly Hills. However, she looked more excited for the occasion than her tots. Weary Mason wiped the sleep from his eyes, clung to his mom's side, and fought for her attention, while baby Penelope yawned.

Kourtney was dressed for the spring heat. She wore a loose white top with belted, over-sized linen pants. The casual look matched Penelope's simple pink and white floral piece, but was drastically different from Mason's getup. The three-year-old must have inherited his dad Scott Disick's eccentric style; he wore a black tank and matching sweats with large white stars.

Kourtney and sister Khloe will make an appearance today at the Huntington Beach Ulta Beauty store to promote their Kardashian Beauty collection.

Kristin Cavallari and Jay Cutler secretly wed yesterday in Nashville.

The couple, who already have a son together, got a marriage license on Friday morning and had the wedding ceremony at Woodmont Christian Church the following day in Tennessee. Kristin Instagrammed a photo of their gorgeous wedding bands and wrote, "Im officially Kristin Elizabeth Cutler!!!!!" after going to Davidson County Clerk's office on Friday. We're not sure why the former Laguna Beach star and the Chicago Bears quarterback chose Nashville as their wedding destination, but Jay did attend college in the area.

We couldn't be happier for these two lovebirds. They first got engaged in April 2011, but called off their wedding two months later only to reconcile and have a baby in August 2012.

Paris Jackson was transferred to UCLA Medical Center from Children's Hospital Los Angeles yesterady evening after ending her 72-hour psychiatric hold, TMZ reports. This is the same hospital where her father Michael Jackson passed away almost exactly four years ago.

The teen was initially rushed to West Hills Hospital and placed under psychiatric evaluation after allegedly cutting her wrist with a meat cleaver and consuming an excessive amount of Motrin pills on Wednesday morning at her Calabasas home.

A judge has ordered an investigation into Paris' suicide attempt to determine whether her "health, education and welfare" had been compromised under her grandmother Katherine's guardianship. After a court investigator presents the findings to a Superior Court judge, Paris may be placed under another family member's custody.

Celebrity children have to stick together!

Gwen Stefani and Gavin Rossdale took their sons to Jessica Alba's daughter Honor's fifth birthday yesterday. Who knew that Kingston and Zuma rubbed tiny elbows with Honor and Haven? Celebrity stylist Rachel Zoe's husband, Roger Berman, and his son Skyler also attended the star-studded birthday bash.

The fashionable family looked the epitome of rocker chic as they walked to Jessica's Los Angeles home. Gwen donned a plain white tank, boyfriend jeans, and sexy black heels with chunky silver chains. Gavin also sported his signature look: a black tee, funky pants, and high tops. Their children have evidently inherited their unique sense of style. Little Zuma wore trendy tangerine jeans, while Kingston stepped it up a notch with belted white jeans, a collared salmon shirt, and brown boots. After the party, Gwen and her men visited her parents' house.

The double dates keep on coming!

Ashton Kutcher and Mila Kunis vacationed with Princess Beatrice of York and her boyfriend Dave Clark today in Saint Tropez. Things must be heating up between this foursome; a group vacation means serious business. The two couples and their friends hit the high seas, boarding a boat at the Le Club 55 beach club and restaurant to head back to Beatrice's yacht.

Mila and Ashton wore matching jeans and flip flops for the occasion. Mila also sported a nautical cardigan that didn't quite cover up her enviable v-cut, while Ashton donned a Panama hat.

Mila has the weekend off from filming Jupiter Ascending so she jetted from London to Nice to join Beatrice and Dave on their French getaway. Oh, the lifestyles of the rich and famous.

Kim Kardashian sure loves social media displays of affection.

After posting a Keek video of herself preparing dinner for her beau Kanye West earlier last week, the reality star has now Instagrammed a collage of their favorite photos in honor of his 36th birthday. She also wrote "Happy Birthday to my best friend, the ❤of my life, my soul!!!! I love you beyond words!" All together now, "awww"!

The couple, who first started dating last April, is expecting their first child together next month. After their baby girl is born, Kim will join Kanye on his European tour. The busy rapper will be headlining the Governors Ball Music Festival tomorrow in New York City. This baby is going to be so worldly!

Maybe they'er the two subjects of Ben Affleck's new film Runner, Runner.

Jennifer Garner and her daughter Violet ran hand-in-hand while leaving school yesterday in Brentwood. The gleeful girls must have been thrilled for the weekend.

On break from filming her latest film Draft Day in Ohio, Jen has been keeping busy with mommy duties. After dropping off Violet at school, she picked up Seraphina from a friend's house, then brought Violet back home. All three ladies looked lovely, but little Seraphina stole the spotlight in her trendy outfit. Denim jacket? Check! Colored jeans? Check! Biker boots? Checkmate! Jennifer's youngest daughter looked especially adorable with her purple-rimmed glasses, red hair bow, and chocolate cupcake in hand. Jen and Ben seem to have a fashionista on their hands.

Even Queen Bey needs a break every now and then.

Beyonce and Blue Ivy took a vacation to rejuvenate before the singer kicks off the U.S. leg of her Mrs. Carter Show World Tour at the end of the month. Bey documented the tropical island getaway, even sharing rare photos of her daughter, on her Tumblr. In one adorable shot, Blue rested on her mama's chest in a hot tub. The singer looked picture ready in a leopard-print turban and over-sized sunglasses.

Other photos included shots of her biking, lounging in the grass, and adjusting the white wrap that she wore over her silver bikini.

She took to Tumblr last week to post photos of herself drinking wine with hubby Jay-Z -- no doubt her way of refuting pregnancy rumors. The new bikini shot serves a similar purpose. Bey is just too bootylious for us.
