Hollywood's A-list came together, as they do every year, for producer Joel Silver's annual Memorial Day party in Malibu.

This year's event brought out the likes of Gwen Stefani (and her three kids in tow), Kaley Cuoco and her hubby, Diane Kruger and Joshua Jackson, January Jones, Cindy Crawford and Rande Gerber, Tobey Maguire with wife Jennifer Meyer and kids, Kate Beckinsale and her husband and ... drumroll, please .... Barbra Streisand and James Brolin!

The family-friendly event featured tons of food and drink, of course, but also a bounce house for the kids on the sand. It was a perfectly sunny day in Malibu -- great for a day on the beach and a BBQ and these stars lived it up!

Send us an Evite next year, Joel!

Grandma Kris has it all under control!

Mama Jenner carefully stroller baby North West through LAX Monday as she and her gaggle of girls returned from Paris after Kim and Kanye's wild wedding week.

While Kimye honeymoon in Ireland, Kris has Nori's care fully under control. Heck, she raised six kids, didn't she? She must know what she's doing!

Daughters Khloe, Kendall and Kylie were close by, as was Bruce Jenner -- who seems to be cozying up to estranged wife Kris, these days. And check it out ... he's got his wedding ring back on, too!

With all this wedding bliss around them, you think Kris and Bruce could be headed for a reunion???

Starting anew? Or just losing it? We aren't sure why Rob Kardashian has deleted all of his tweets after skipping out on Kim Kardashian and Kanye West's wedding at the last minute -- but it's definitely a bit odd.

On Memorial Day, the sometime reality star/sock designer tweeted "good morning from Los Angeles" to his almost five million followers and then deleted ALL of his tweets. The lone Kardashiain man then changed his Twitter avatar and proceeded to tweet some possibly inspiring/definitely worrisome tweets about God, Jesus and firefighters.

We have no problems with any of those things -- but it just seems like these bizarre tweets are cry for help in the wake of his shocking departure from France on Saturday, just hours before Kimye's Italian wedding.

What's with all the drama? A source told X17online, Kim and Rob had it out Friday before the lunch at friend/designer Valentino's chateau. Kim wanted the departure from Paris to look like a catwalk, with every member of the Kardashian clan wearing beautiful Valentino couture and looking like a million bucks. Obviously Rob didn't fit into that plan and that's when the war began ...

The source added, "Rob said he was sickened by Kim and Kanye's display of wealth and clothes and beauty and called it 'superficial bullsh*t' but Kim was pissed that Rob hadn't made an effort to drop any weight over the past few months. Rob basically thinks Kim cares about him only for his appearance and he said he'd 'make life easier' for her and just leave."

Oof, that sounds rough! We really hope Rob gets some help -- he seems to be very unhappy and his family seems to be too busy caught up in the Kimye fanfare to notice.

It's tulle time for Lady Gaga!

The outrageous singer looked almost demure over the weekend-- almost! The bold hit maker took to the means streets of Manhattan on Sunday, dressed a bit like a princess -- and we are kind of wild about this look.

Exiting her apartment, the 28-year-old flashed a smile as she was dressed in a billowing pink chiffon dress, under a beige coat, belted at the waist and combat boots. The "Applause" singer wore her constantly changing tresses down and shielded her eyes with a pair of cat eye sunglasses.

The singer was enjoying a two-day break from her ArtRave: The Artpop Ball at her home of New York City.

On Saturday, the usually busy singer boasted of her mini break, writing, "This is the best day off ever. I really needed it! I have not left my bed and it feels like heaven! #slumberparty."

That definitely sounds like the best day ever to us too!

Uhh this doesn't look good for a lot of reasons!

On Sunday Real Housewives of Beverly Hills star Brandi Glanville tweeted that she was at the hospital yet again with her son Mason yet again, due to another allergic reaction.

"At ER with Mason 3 rd time in 9 weeks :/ allergy's and Epi-pens suuuck! Better safe than sorry #lovesofmylife (sic)," wrote Eddie Cibrian on Sunday.

Later on Sunday, the leggy 41-year-old tweeted the above pic of Mason in a hospital bed with younger son Jake making what looks like a gun with his hands, along with the caption, "My little patient and his not so sympathetic little brother."

Uhh we aren't sure that in the wake of the UCSB tragedy posting an image of young boy who looks like he's acting out play guns with his hands is totally appropriate -- but we guess we are talking about Brandi Glanville. Appropriate is clearly just not her thing.

Appropriate pic or not -- we sure hope Mason is okay!

Meanwhile, Mason's step mom LeAnn Rimes had quite a different weekend. Before the youngster's health scare, the blonde went for a facial at Tracie Martyn's New York spa. The actress-singer went casual in a hat, jeans and t-shirt.

At least one of Eddie's ladies had a relaxing time!

Everyone has the day off! So what do A-listers do when they have a holiday weekend? Spend time with their kids of course! Reese Witherspoon, Gwen Stefani, and more were out with their oh-so-sweet offspring over the weekend, as they enjoyed some time off for the Memorial Day holiday.

On Saturday, Reese Witherspoon carried her tow-headed son Tennessee for a family lunch in Brentwood. The Oscar winner grabbed some grub with daughter Ava, Deacon, Tennessee and hubby Jim Toth.

On Sunday, Gwen brought baby Apollo for a visit a friend in Los Angeles. For the afternoon event, the stylish singer wore a bright orange code, studded jeans and her often worn yellow loafers. She outfitted her baby boy in a white top and turquoise pants. Gotta love it!

Even new parents Olivia Wilde and Jason Sudeikis were enjoying the soon-to-be summer sun as they went for a Saturday stroll with their bundle of love, Otis!

Off-again/on-again couple Hilary Duff and and a very thin Mike Comrie looked very happy together as they enjoyed time with their toddler Luca on Sunday in Brentwood.

Check out these proud parents and more who are busy hanging out with their wee ones!

Now THIS pairing we like!

Justin Bieber pulled a serious swagga move and invited superhot Guess model Gigi Hadid on his boat in Monaco. Of course Gigi is newly single after a recent breakup with Aussie hottie Cody Simpson. Frankly, we think Bieber's a BIG step up!

Gigi, 19, is the daughter of Beverly Hills Housewife Yolanda Foster and is no stranger to the jet-set lifestyle. Justin, 20, was in Cannes for the film festival and is now in neighboring Monaco for Formula 1 Grand Prix.

Will Selena feel the need to tweet something about this?

Baseball hat! Dirty converse! Ratty shirt! Sounds like Kristen Stewart's back to her old habits soon after leaving Cannes' glittering croisette!

Soon after her time at the French Film Festival came to a close, sullen actress Kristen Stewart traded in her couture for Converse -- and we aren't surprised even slightly. On Sunday, the 24-year-old arrived back to Los Angeles from France wearing her unusual uniform of dirty shoes, sweatshirts and jeans.

When she boarded the plane, the Twilight star wore a sparkly white Chanel outfit. Knowing K-Stew, she probably switched up her style as soon as she got past security!

We get it Kiki, life is just so hard for a world-famous actress who is also the face of Chanel!

Robert Pattinson's former flame was in Cannes promoting her critically acclaimed film, The Clouds of Sils Maria.

The movie, which is directed by Olivier Assayas, follows an aging actress Maria Enders (Juliette Binoche) who signs on to be in the revival of the play that made her famous twenty years previously. While the play is the same, everything else is different this time around. Maria will now be playing the role of the older woman and a young Hollywood starlet (Chloe Grace Moretz) will be the lead. In addition, Maria has a very intense relationship with her assistant Valentine (Stewart) and possible lover. The two go into the Swiss Alps to work on the play as tensions build.
