On Saturday Jennifer Garner took her three children to the Los Angeles Natural History Museum and California Science Center, and it looks like everyone had a blast!

Earlier this week, Jen was busy shooting her new movie, Imagine, and on Friday she went to a meeting with hubby Ben Affleck, but rather than holding hands on the way out, the duo made separate exits. If it was anyone else we'd question whether there was trouble in paradise, but given how hectic Ben's worth schedule is, it looks like they're just super busy!

On Saturday Heidi Klum and Martin Kristen went for a joy ride in Brentwood, and the supermodel/TV personality held on tight to her man.

When she's not busy looking after her four kids, promoting both of her shows and squeezing in quality time with her beau, Heidi is already thinking about Halloween!

Earlier this week she posted an Instagram photo of her face covered in clay getting fitted for a mask and wrote, "Started working on my Halloween costume! #HeidisHalloween." Can't wait to see what she goes as this year ... even if it is three months away!

On Saturday Jessica Alba went shopping with daughters Honor and Haven in Brentwood, and we love that she put her darling little girls in matching outfits! Honor looked excited about it, but little miss Haven seemed to be a bit grumpy. Aww, but she's still so cute!

In case you're wondering how Jessica still looks so amazing after two kids, she revealed some of her secrets in the new issue of Women's Health.

“After both pregnancies, I wore a girdle! People have been doing it for years," Jess confessed to the mag. "And, let’s face it, I don’t have the body of a 14-year-old anymore. I think the more we try not to have that unrealistic ideal, the happier we’ll be.”

When it comes to her diet, Jess said, "I like a naughty treat as much as the next person, but I’ve tried to change my taste buds. So if I’m craving something salty, I’ll have dried seaweed or almonds. Rice crackers and Popchips are also good. If I need a sweet fix, I’ll stick to natural sugar. Who can say no to fresh cherries or strawberries?"

Jess admits that she has "cellulite and stretch marks and a muffin top," but we're still trying to figure out where ... we never see it!

Elle Macpherson and her billionaire beau Jeffrey Soffer got married in Fiji, according to Us Weekly. The couple, who announced their engagement last March, were with family and friends.

The duo dated for two years and ended their romance in March of 2012, but they got back together six months after that when Soffer hurt his back in a helicopter crash.

Macpherson was previously married to fashion photographer Gilles Bensimon from 1986 to 1989, and she has two sons from her long term relationship with Arpad Busson, who is currently with Uma Thurman.

Jennifer Aniston left a press junket in New York City on Saturday to promote her new flick, We're The Millers, and the 44-year-old actress didn't stop to sign autographs, but she did smile and wave to fans!

We weren't really able to get a good look at Jen's tummy, but after looking at photos of Jen's tummy on the red carpet the other night, we have to wonder if she's preggers. And we're not the only ones! After getting a peek at what looked like a possible baby bump, even USA Today wrote, "Maybe it's the old I-ate-a-cheeseburger-and-a-couple-of-buns. Or maybe the other kind of bun is in there." Plus then there was those IVF rumors earlier this week, which could explain it if it's just a weight gain...

Anyway, Jen's BFF/hairstylist Chris McMillian posted the shot below on Instagram before doing her hair and wrote, "Best #friends #no makeup #girl-time." We know he loves her, but how does she feel about this pic?

This one might be even better than the first!

From Amber Heard and Lady Gaga looking smokin' hot to Sofia Vergara unloading bullets from her bra, we can't wait for Machete Kills! In the latest installment from Robert Rodriguez, the U.S. government recruits Machete to take out an arms dealer in Mexico.

Vanessa Hudgens, Michelle Rodriguez, Jessica Alba, Charlie Sheen and Mel Gibson also star in the film, which hits theaters on October 11.

After the news broke on Friday that Megan Fox and Brian Austin Green were expecting their second child together, the couple jetted from Los Angeles International Airport to New York City.

Brian Austin Green pushed their 10-month-old son, Noah, in a stroller and the former Transformers hottie hit her baby bump with a baggy tee and a green tote. A few hours before these photos were snapped, the starlet's rep confirmed that baby number two was on the way, adding, "They are both very happy."

I guess these two weren't in the mood to hold hands after a meeting on Friday!

After taking care of business, Ben Affleck and Jennifer Garner made separate exits from a building in Beverly Hills, and we're just wondering why they weren't their usual lovey dovey selves. Maybe Ben was in a rush to another meeting? With back to back movies this summer and fall, the next few months are going to be pretty packed for the 40-year-old Oscar winner!
