We don't see a difference yet, but we have a feeling a transformation is in the works!

Rob Kardashian was a busy bee yesterday as he filmed Keeping Up with the Kardashians in L.A., and he must be feeling more confident with his physique because he was rocking leather pants!

It seems everyone in Kim K's family is borrowing her boyfriend Kanye West's signature style! Just the other day, Kourtney's baby daddy Scott Disick hit the town in a pair of leather pants, and Khloe wore a leather dress to film yesterday. Yeezy has turned the whole clan into a bunch of leather lovers!

After gaining more than 50 pounds following his break up with British pop star Rita Ora, the 25-year-old sock designer has vowed to shed the unwanted pounds and get back to fighting form!

"It's crazy how this whole year, my whole relationship was only negative. All I did was gain f**king 40 pounds and lose so much money. I'm so insecure. I weigh like 215 pounds. I hate pictures. I hate everything," he recently revealed on an episode of Kourtney & Kim Take Miami.

The reality star is already taking matters into his own hands, as he frequently tweets pics of his healthy meals and hits the gym daily.

You can do it, Rob!

What a cute trio of travelers!

On Wednesday night Kate Hudson was snapped shortly after landing at Los Angeles International Airport, and she was joined by sons Bingham and Ryder. Kate's beau Matt Bellamy had tour dates in Canada and the UK earlier this month, but when he came to Florida last week for three back-to-back concerts, Kate decided to join him for some fun in the sun.

So will the couple be getting married anytime soon? Not likely! She recently told Closer magazine, "Now it’s just nice if we manage any time together because we have a 19 month old and a nine year old! We will get married, but we just don’t know, where or what. We just have no time."

Maybe he HAS turned a new leaf!

Chris Brown was snapped filling up at a gas station in Los Angeles on Wednesday evening, and he happily struck a pose for photographers while he waited. We aren't sure where lady love Rihanna was, but it looks like maybe these two young lovers have grown up a bit over the years.

Last month Rihanna opened up to Rolling Stone about their relationship and said, "It's different now. We don't have those types of arguments anymore. We talk about sh*t. We value each other. We know exactly what we have now, and we don't want to lose that." At first we didn't believe her, after Chris' comment that hitting her was the "deepest regret" of his life, we're more inclined to buy it.

After going to rehab last September, Billie Joe Armstrong has given his first post-treatment interview to Rolling Stone.

The Green Day rocker opens up about his alcohol and prescription drug abuse and what made him decide to get finally help. "I couldn't predict where I was going to end up at the end of the night," Armstrong says. "I'd wake up in a strange house on a couch. I wouldn't remember how. It was a complete blackout."

But it wasn't until Armstrong's bizarre meltdown at the iHeart Radio Music Festival last fall that he realized he had a problem. When producers at the concert turned on a "one minute" sign left for their show, Armstrong began shouting and smashing his guitar on stage. "I'm not f*cking Justin Bieber, you motherf*ckers," he yelled. "Let me show you what one f*cking minute means."

Armstrong says he only remembers "tiny things" from the incident, adding, "The next morning, I woke up. I asked [my wife] Adrienne, 'How bad was it?' She said, 'It's bad.' I called my manager. He said, 'You're getting on a plane, going back to Oakland and going into rehab immediately.'"

On Wednesday Kim Kardashian spent some time with her mom Kris and sister Kourtney, then she had a quick outfit swap, then she posed for photos with fans and finally she shot her reality show for a few hours. We don't know how she has time to do it all!

So what about recent reports that Kim and baby daddy Kanye West are expecting a girl? When asked about it yesterday, Kim told our videographers, "No one from my camp confirmed that ... you didn't hear it from me!"





Meanwhile, Khloe and step dad Bruce Jenner were across town shooting a segment for the show that involved eating pizza and cuddling with puppies:



Their day sounds like WAY more fun! Click thru to watch video of Khloe and Bruce...

Given her track record with relationships over the past year, we're surprised Ashley Tisdale and Annie Automatic rocker Christopher French are still going strong, but they are!

On Wednesday Ashley and her inked up boyfriend grabbed a bite at Hugo's in Studio City, and the couple held on tight to one another as they left the restaurant.

"She likes those rocker types," an insider told Us Weekly when the lovebirds first stepped out together in late December. "They have mutual friends and just met through hanging out."

After ending her two-year relationship with director Scott Speer in late 2011, she briefly dated Boys Like Girls lead singer Martin Johnson, but then she got back together with Speer in 2012, only to split from him again late last year. Hopefully her romance with this tattooed hottie will withstand the test of time!

They don't do everything together, mind you!

On Wednesday Gavin Rossdale and wife Gwen Stefani went their separate ways, as Gavin worked up a sweat at the gym while Gwen was snapped with son Zuma at a local park.

But is it possible that Gwen raided her hubby's closet for a pair of baggy jeans while he was getting his sweat on? She almost always wear skinnies, so we can't help but wonder if she decided to switch it up with a pair of her very own boyfriend jeans...

She may be expecting baby number two, but Jessica Simpson is determined to stay in shape!

After gaining over 70 pounds during her first pregnancy, the singer/actress has been making regular trips to the gym, and we're guessing that multi-million dollar Weight Watchers deal is also probably keeping her grounded when it comes to raiding the fridge.

Of course, not everyone is happy about Jessica's $4,000,000 payday. One of the company's disgruntled group leaders recently told the New York Times, “We are professionals, we have to dress nice, but we are paid less than kids who work at McDonald’s." According to the article, Weight Watchers leaders earn as little as $7,600 per year.
