Who needs summer camp when you can hire a few REI guides to take your kids on a private bike excursion?

The other day Shiloh, Knox and Zahara Jolie-Pitt enjoyed the great outdoors while pedaling around a park in Malibu, and we're not sure where Vivienne, Pax and Maddox were, but these three certainly had a good time! Knox and Zahara didn't need training wheels, but they did ride on the back of a tandem bike ... well, a tandem attachment anyway!

Meanwhile, we snapped Angelina Jolie on the set of Unbroken, texting away as her kids played. Maybe she was coordinating their next activity?

As usual, Honor Marie Warren certainly knows how to keep us entertained!

On Labor Day Jessica Alba and hubby Cash Warren grabbed some groceries at Bristol Farms in Beverly Hills, and on the way in their oldest daughter Honor flashed photographers a series of silly faces. Wonder if she learned a few of these from her mom?

Over the weekend Jess and Cash hit the beach in Malibu, and even though the 32-year-old actress covered up her hot bod in a floral-print kimono, we still got a peek at her amazing abs in a bright purple bikini. In case you missed those pics, check out the full gallery HERE!

You'd never know how much drama Khloe Kardashian was dealing with after seeing these photos ... maybe she really is made of steel after all!

On Monday the reality TV starlet attended a Labor Day bash at Katy Perry's new Hollywood Hills pad, and she flashed X17 photogs what appeared to be a truly genuine smile on her way in the door. Khloe also flashed her wedding band and massive engagement ring, so even though estranged hubby Lamar Odom was arrested for D.U.I. last Friday, it looks like she still hasn't given up! Or that's what she wants us to believe, anyway...we can't even keep track of how many times she's taken her rings on and off now!

Just days before Lamar's D.U.I arrest, his teammates and agent attempted to have an intervention with the NBA star to confront him about his alleged drug use, but it was reported that he left and didn't want their help. However, the very next day Lamar spent the night with Khloe at the couple's Tarzana mansion, and the following day we snapped him grabbing a bite at Taco Bell and returning home once again, so it seemed like things were getting better for a while. Over the weekend Lamar rented a bunch of DVDs and seemed to be planning a solo movie night, but so far the Kardashian family has yet to announce that the couple have officially split.

And speaking of being in a great mood, looks like the hostess was having a blast:

She's just bein' Miley!

It may have been Labor Day, but rather than hitting the beach or heading to a pool party, Miley Cyrus busted her booty at the recording studio on Monday afternoon. And no, she wasn't twerking here ... just extinguishing her cigarette on the ground after puffing away with a few pals. But what's with the middle finger, Miles? She tweeted, "ain't nobody got time for that #BS..." Wonder who that message was intended for?

The other day Sunday People posted an interview with Miley, and the 20-year-old starlet revealed that she is a self-described workhorse who only sleeps 45 minutes a night sometimes. Miley added, "I have so many f**king issues ... I am so f**ked up."

Maybe once she's done with Bangerz she should take a vacation before heading out on tour? We don't want our Miles having an Amanda Bynes-style meltdown!

And not only that, but this is the director's cut, so there's some extra sexy scenes in here!

Rob Pattinson may have said that he doesn't wear cologne and that he hates his RPatz moniker, but after watching this steamy Dior Homme ad campaign video, all is forgiven. Seriously ... why wasn't Twilight this hot?!

The black and white vid is set to Led Zeppelin's "Whole Lotta Love," and between making out with models and sitting in a bathtub, you must watch!

P.S. Rumor has it the 27-year-old actor was paid a whopping $12 million to be the brand's newest spokesmodel ... not a bad deal at all!

Hot mama!

Jessica Alba and her family spent the Labor Day weekend in Malibu soaking up the sunshine, and the actress looked simply stunning a purple bikini and floral cover-up. We can't believe she's had two kids!

The Sin City star and her brood were joined by celebrity pals like Samantha Ronson.

The brunette beauty makes balancing family time with her career look easy, but she insists it's not as seamless as it appears.

"Tell me if someone's figured out how to perfectly balance it all. Because I am still trying to figure that one out. I think balance just comes with your attitude and trying not to live up to anyone's idea of perfection, of who you should be, and cutting yourself some slack at the end of the day. I think that's really what it comes down to - and you know, as much as you can balance your time between work, friends, kids and all the different roles that you may or may not fill," she recently told Editorialist.

Nothing like a beach day with your babies!

That call must be really important! A wide-eyed Gerard Butler was photographed on Sunday talking on his phone while at LAX.

The 43-year-old actor touched down in Los Angeles after a traveling from Barbados.

Recently, the great Scot purchased a stake in a West Indies cricket team called the Jamaica Tallawahs.

Butler explained his decision to lay down some cash, "I've had the opportunity to watch some of the matches. It is obvious that this tournament is the home of the greatest party in sport so I wanted to get in on the fun. As a Scotsman, I definitely have an appreciation of cricket.”

Maybe Butler was talking cricket shop during his seemingly intense phone call!

The 43-year-old will next lend his voice to the role of Stoick the Vast in How to Train Your Dragon 2, due out in 2014.

Not only do we love love love her khaki skinnies, but that smile? Gorgeous!

X17 photographers caught Ali (er, Aliana?) Lohan out and about in New York City over the weekend, and Lindsay's little sister worked the sidewalk like a catwalk when we snapped her picture.

And speaking of Lilo, she's been laying low since getting out of rehab in late July, but rumor has it she was asked to host the season opener of Saturday Night Live! Lindsay has hosted the show five times now, and even though her last effort wasn't a smash success, she guest-hosted Chelsea Lately last month and booked a guest spot on Eastbound and Down, so things are definitely looking up for her.

But back to Ali ... even when she's not smiling, shes still stunning:
