Heidi Klum stepped out with her kids at Michaels in Los Angeles on Saturday, and if we didn't know any better we'd ask if the former supermodel was pregnant!

This would be her fifth kid (her first with current beau Martin Kristen), and just the other day she wore a peplum dress that pretty much concealed the lower part of her midsection, so we gotta ask. Heidi has been dating her bodyguard/beau for about a year now, and the two began their romance about nine months after her split from Seal in 2012.

Do you think Heidi is preggers? Or did she just pick the wrong top?

Sparrow Madden certainly had one heck of a guest list at his 4th birthday bash on Saturday afternoon!

From Jessica Alba to Gwen Stefani to Kourtney Kardashian, some of Hollywood's hottest moms brought their kiddos to celebrate with Nicole Richie and Joel Madden's son at a hotel in Beverly Hills.

Joel helped wrangle the guests, and speaking of kids, there's still no word on whether Gwen is really pregnant with her third child, but she's definitely keeping us guessing with her outfits:

Aww, how cute is this!

On Saturday Reese Witherspoon went shopping with son Tennessee and daughter Ava, and the Oscar winner was more than happy to let her teenage daughter carry her one-year-old son.

Not sure where Tennessee's big bro Deacon was, but last weekend we spotted him with Reese and hubby Jim Toth grabbing some goodies before a Labor Day BBQ. Maybe he was hanging with dad Ryan Phillippe this weekend?

This week Reese will make her way to the Toronto International Film Festival to debut her new movie Devil’s Knot, which is a drama about the West Memphis Three.

Newly engaged Ashley Tisdale shopped at Intermix in Beverly Hills on Friday, and the starlet carried our fav Celine bag and showed off her toned and tanned bod in a pair of white shorts. What a rough life she's got!

While she is voicing a character on the upcoming Phineas and Ferb movie (in case you didn't know, she's voiced Candace Flynn on the TV show since 2007!), there are no other big roles for her this year.

She's certainly not busy planning her wedding, because after the news broke that Christoper French had popped the question, Ash told People, "I want to make sure it's perfect! But it's going to be a while. I started a Pinterest board, but I'm not one to rush anything. For me, it's stressful just thinking about my birthday, so I can't imagine my wedding day!"

We can't imagine what she's going through right now, and while she's not stepping out in public, Khloe Kardashian has been posting lots of sexy selfies over the last few days. And you know what? She seems to be handling her marital drama (not to mention rumors that estranged hubby Lamar Odom has gone missing) like a pro.

On Friday evening Khloe tweeted, "Night....... You know the drill ... I wish it were night forever." An hour or so later she posted the selfie above and simply wrote, "White Noise."

Not sure what that means but we do love to see her smile!

He may only be 19, but that's not a problem!

On Friday night Patrick Schwarzenegger stopped by Pearl's Liquor Bar on Sunset Blvd, and he was joined by none other than Twilight star Taylor Lautner! While the venue serves alcohol, they're also a restaurant, so Patrick was allowed in, even though he's under 21. Whew!

Patrick's dad Arnold recently talked with Daily Express and gushed about his oldest son, telling the publication, “I’m so proud of him. It’s not easy having a father like me and having to emerge with his own career. But he’s not only working hard, he’s studying hard, going to college and learning business. Half the people who make it in Hollywood lose their money so you have to learn to look after it. That’s why I’m so pleased he’s learning business just like I did. It means he won’t lose his money because of some shyster."

Vanessa Hudgens took a break from shooting Kitchen Sink in Los Angeles on Friday afternoon, but don't be fooled by the cute outfits -- she's battling all sorts of bad guys (and girls!) in this flick.

According to a plot synopsis on IMDb, "Vampires, humans and zombies used to get along in Dillford, but then something unexpected arrived and now it's humans vs. vampires vs. zombies in all-out mortal combat. It's up to three teenagers to try to get things back to normal."

Bob Odenkirk, Ed Westwick, Joan Cusack and Denis Leary also star in the film, which is expected to hit theaters next year.

On Friday afternoon Kendall Jenner was snapped out and about near the Kardashian family compound in Calabasas, and she wasn't quite in the mood to smile for the cameras but she did show off her gorgeous gams in a pair of short shorts!

Later in the day the 17-year-old tweeted the photo below and wrote "new hair?" but she later wrote, "jokes, jokes." We're not sure if she followed in big sister Khloe's footsteps and went for the ombre look or if this is just a tease, but we love it!
