Talk about multitasking!

If you're going to be filming a reality show on Melrose Ave., why not sneak a little shopping trip into the schedule?

Kim, Khloe and Kourtney did just that, as they took over the popular West Hollywood street to film scenes for an episode of their upcoming Keeping Up with the Kardashians series, on Saturday afternoon.

Now that Kim has kind of warn out the whole idea of a "wedding" episode this season, it's a good thing Kourt is preg -- but when will her wedding actually be? And while it's a little harder to keep up with Khloe now that hubby Lamar Odom has been traded from the Lakers to the Texas Mavericks, we can't help but wonder when baby No. 1 will be on its way!

Find out what Khloe had to say about her "baby bump" in our exclusive video below!

Don't mess with these bad boys!

Taking advantage of some time off from mom Gwen Stefani, Kingston and Zuma spent the day riding bikes and scooters, discovering nature, and generally hamming it up for the cameras in LA, on Saturday afternoon.

We particularly love how Kingston's learned to throw up a peace sign -- what a little gangster!

These boys' nanny definitely has her hands full!

Special delivery for January Jones?

We kid, but Zach Galifianakis was definitely in a hurry to deliver a lovely bouquet of purple flowers as he sped though Venice on his metallic green Vespa in a sexy red helmet, on Saturday afternoon.

It was recently announced that the funny man is set to star in the third and final installment of The Hangover alongside costars Bradley Cooper and Ed Helms, in September.

We can't wait for Zach to bust out that satchel one last time!

Could they be any cuter?

Supermodel mom Heidi Klum literally had her hands full as she treated her kids, Leni, Henry, Lou (in a pink tiara!) and Johan to a fun-filled day at The Grove on Saturday afternoon, where they enjoyed ice cream and got to ride the trolley!

Although the former Victoria's Secret Angel is going though a painful divorce from hubby Seal, she's putting all of her focus on her four kids, who looked extremely happy to be spending the day with mom!

Adorbs!

Rihanna may be complaining a bit too much about her "too thin" figure these days, but at least she's feeling more confident naked!

The "S&M" singer recently revealed to Britain's Women's Fitness mag of bearing it all"

"The more I got naked, the more comfortable I felt. I just had to face my fear. You always find something wrong, you always find something you’re uncomfortable with, and one thing turns into another and you get embarrassed and self-conscious about it."

The pop star continued, "After a while, it was like, 'What’s the worst that can happen?' I just started being a little more daring with it. It was just knowing my body … is what it is under clothes or outside of clothes."

Unfortunately for the rest of us, Rihanna admits, "My way probably won't work for most people."

Maybe that explains why Riri's been flashing a bit more skin these days!

We know "The Biebes" has a thing for older women, but a 27-year-old divorcée might be pushing it!

While ex-hubby Brand was prepping to hit up a tattoo parlor with his new Hungarian model girlfriend, Katy Perry was busy grabbing lunch in Hollywood while showing her love for fellow musician, Justin Bieber, on Saturday afternoon.

The "Firework" singer's T-shirt featured the 18-year-old's Rolling Stone cover, which she wore under a grey hoodie, black pants and a LA Dodgers baseball cap pulled over her eyes to cover her bright blue 'do.

Could Perry be wearing the shirt to support Justin, since "Boyfriend," the first single from his latest album Believe, will be released on Monday?

Selena Gomez, watch out!

Is Russell Brand getting that matching tattoo he has with ex-wife Katy Perry removed?

It might be a good idea, considering he's already moved on with Hungarian model Nikolett Barabas, who accompanied the Author star to Mark Mahoney's Shamrock Tattoo parlor on the Sunset Strip in West Hollywood, at 1am on Sunday morning.

Brand already has countless tattoos, but it might be time to ditch the matching ink in Sanskrit which Perry also shares!

While the funny Brit looked sexy in a long black coat, jeans, a black hat and sunglasses, he wasn't looking so stylish earlier in the day, when he stepped out in a sparkly women's blouse, and bright red bedroom slippers.

Not your best look, Russ!

Doesn't this woman own a blow-dryer?

Once again Kate Holmes stepped out of her Manhattan apartment with soaking wet hair as she made her way through the chilly streets of NYC solo, on Saturday night.

Earlier in the day, the hot mamma treated daughter Suri to a shopping spree at the Build-A-Bear workshop, so it's no wonder that Mrs. Tom Cruise looked anxious to get outta the house for an evening of kid-free fun!

Don't catch cold, Kate!
