Kim Kardashian has been busting her booty at the gym and watching what she eats, and four months after giving birth to her first child, she wants to show off the results! We have to say, we're pretty impressed, especially when you consider she gained a reported 60 pounds during her pregnancy!

The curvy reality starlet posted this sexy swimsuit selfie on Instagram last night and simply wrote "#NoFilter," and when asked what her slim down secret was on Sunday via Twitter, Kim replied, "I've actually been doing the Atkins diet & luv it."

"She is eating lots of lean proteins, healthy fats like nuts and avocado, carbs, fruits, veggies and cheese," a rep for Atkins told Us Weekly. "She wanted to be a healthy, nursing mom and not toxify her milk with her diet or lose weight too quickly. She's been doing Atkins since her doctor approved it at the end of June."

We're guessing Kanye loves it too, because he re-tweeted her pic and wrote, "HEADING HOME NOW.” Ha!

Just in time for Halloween! But hopefully this doesn't scare Lamar Odom off...

On Wednesday afternoon Khloe Kardashian drove around near her Tarzana home, and not only is her wedding ring back on, but it looks like she was experimenting with some new makeup hues. And outfits? Earlier in the day she posted the shot below and wrote, "I'm loving our kardashiankollection leopard leggings from Sears! #LeopardLover." Meow!



While Khloe is busy doing her own thing, it looks like her estranged hubby may be making some progress to get his life on track. Though he refused to go to rehab and hasn't been spending much time with Khloe, he met with Lakers coaches earlier this week and Us Weekly reports that the NBA star enjoyed "a long, leisurely lunch" with friends on Tuesday in Glendale. Lamar spent five hours at the Armenian eatery Gavar Cuisine, and at one point during the meal, he held a baby belonging to one of his pals.

"He is trying to show Khloe that he's changing and he wants to make it work," a source tells the mag. "He is working out and looks really good and is happy again. It's so nice to see him getting better."

So does this mean they're going to reconcile? And will Khloe put the brakes on selling their home?

Even when she's running errands, Hilary Duff dresses to the nines!

On Wednesday the actress/singer stepped out in Los Angeles, and from the Chanel bag to the red hot pumps and skinnies, the former Disney starlet looked amazing. Over the weekend Hil took a night off from mommy duty and went to Pink's concert at the Staples Center, and interestingly enough, she recently worked with Pink's producer, Billy Mann.

Hil has been busting her booty in the recording studio this summer and fall, so we can't wait to hear what her new tunes sound like!

Rob Pattinson's buff bod may not stick around for long ... the extra pounds are for his upcoming role as a military interrogator in Mission Blacklist ... or is it breakup weight? Seeing as Rob's rumored to be dating Sean Penn's daughter Dylan and getting his flirt on with various ladies on the Hollywood club scene, we have to believe he's putting on pounds for his new film.

Rob gave us a peek at his beefier arms and torso while grabbing a to-go bag of food in Los Angeles on Wednesday, and he also showed off a serious amount of scruff. So much for our clean-cut Edward Cullen fantasies!

And speaking of film roles, when the news broke this week that Charlie Hunnam had dropped the role of Christian Grey in the Fifty Shades of Grey film, Rob's name was thrown into the mix. But don't worry, it's not what you think!

"[Charlie] dropped out of the project because he didn't want to be typecast," a source tells People magazine. "He didn't want the Robert Pattinson-esque attention that would come along with taking on this role." Ouch! But Rob's bank account is probably ten times bigger than Charlie's, which isn't really the worst thing either...

Apparently even for a mom of two your shorts can never be too short and your stilettos can never be too high! Kourtney Kardashian showed off her gams by wearing teeny weeny cutoffs when she took daughter Penelope for a playdate on Wednesday in Los Angeles. Hey Kourt, who you trying to impress? Oh right -- everyone.

Wearing a bulky sweatshirt, tiny cutoffs and black ankle strap sandals, the petite reality star carried her 15-month-old daughter to her afternoon of fun.

With sister Khloe and mom Kris' marriages on the rocks, Kourtney seems to be captaining the most successful Kardashian relationship. Who would have thought?! We have to say we are shocked that Kourt and Scott Disick are still holding strong all these years later.

Maybe all the Kardashian women are like those witch ladies in "Practical Magic" and are cursed with unhappy marriages and all they need to do to be happy is to sing and dance around and just never get married!

This would be huge!

Lamar Odom looked like he was on the road to recovery back on October 1 when we snapped these exclusive photos, and not only did the NBA star reportedly meet with his former Los Angeles Lakers bosses earlier this week, but now TMZ is reporting that he's in talks to do a sit down with Oprah Winfrey.

Oprah and Lamar haven't come to an official agreement or set a date, but the website reports that topics will include Lamar's drug use, his troubled marriage to Khloe Kardashian and his future in basketball. "Lamar is game if the conditions are right," the site reports.

Wonder how much of a pay day he'd get for this? After all, Lindsay Lohan got $2 million for her first post-rehab interview and an eight-part docu-series, so maybe Lamar could get something in the seven-figure range as well? Or at this point is he just trying to preserve his reputation?

We applaud her bravery!

Mischa Barton appears on the newest cover of People and opens up about her rise to fame and how Hollywood pressures led to her much publicized stint in the psych ward back in 2009.

"It was a full-on breakdown. I was under enormous pressure," she confessed to the mag about being placed on an involuntary 5150 hold after she threatened to kill herself.

The former "It" girl took the event as a wakeup call and focused on getting healthy, but even then she was forced to deal with cruel headlines, specifically about her size.

"It was always, 'She's too skinny, she must be sick.' Then it was, 'She's too big.' I was never the right weight," she explained.

With a new movie, TV pilot, and London boutique occupying her time these days, the OC star is staying focused on the positive.

"I've learned a lot. I'm stronger now," she insisted.

We're happy she's in a better place!

She needed something to love!

Lea Michele is slowly healing her heartache following the July death of boyfriend Cory Monteith, and the Glee star recently adopted a Pomeranian mix to help her cope with her grief.

The actress shared a snapshot of her new pooch on Twitter with the caption," Today I would like to introduce you to Pearl. She's 8 years old and is my new little love... Welcome Pearl."

It's good she has a new fuzzy friend to keep her company!

"[Lea] still misses him every day. She talks about Cory all the time. [Lea] doesn't like to be alone. Her friends have really been helping her through it. It's getting a little easier," a source dished to People.

Animals always make people smile!
