In case you didn't know, this is the fine art of skateboarding while hanging on to a moving vehicle -- not exactly the safest thing to do in in a big city where there's tons of traffic!

But Justin Bieber did just that on Saturday afternoon, and while this isn't exactly helping to clean up his bad boy image, keep in mind he's just 20. Not like that makes this excusable, but certainly a little bit more understandable. Boys will be boys!

Biebs posted the Instagram video below and wrote, "Ridin down fairfax lol had a great time." Bieber is a pretty skilled skater, and he frequently practiced on the ramp at his old Calabasas home, so we're not so concerned about him as we are about a crazy fan or a careless driver. But hey, as long as he's not going tooooo fast, this doesn't seem that bad, right?





Before his little adventure, Biebs stopped by the Joyrich store to pick up a new hoodie, and when he left, he flashed us a quick smile and a peace sign:



Gotta love it!

Here comes the bride! Well, not quite yet...

On Saturday morning X17 photographers snapped Kim Kardashian arriving at her bridal shower at The Peninsula Hotel in Beverly Hills, and she was joined by all of her sisters along with pals Ciara, Brittny Gastineau, Rachel Roy, and Shelli Azoff.

Though the reality starlet was perfectly done up, she looked a bit stressed! With her wedding to fiance Kanye West just two weeks away, it sounds like she has a lot on her plate -- and she hasn't even ironed out her prenup or signed her marriage license!

Prior to writing a blog about racism in society, Kim posted a series of tweets addressing rumors about her wedding. “Seeing so many different reports not gonna start disputing them all but a few I want to straighten out," she wrote, adding that the duo are not married (e.g., they haven't actually inked their license in the state of California), they won't be televising their wedding and "no one" has seen her dress. "That's it!" she added. "Unless you hear it from us please don't believe nonsense!"

Kris recently sat down with E! News and revealed that she doesn't know what exactly is going on with her daughter's upcoming nuptials. "Kim and Kanye have done this all on their own and they've had the best time planning it and I know nothing," she said. "I have not seen her wedding dress, I don't know how she looks in it. I'll see it for the first time when she puts it on at her wedding."

She added, "I'm really excited. I've never been able to just go some place and relax and enjoy the ride and let everybody else worry about everything because I'm such a control freak. So this has been a little bit of a lesson. It's a bit hard for me to let go and it's an exercise of patience and I'm sorta a control freak so to sit back and relax…this isn't easy for me either! I'm going into this with a great deal of excitement. I was a little bit curious at first and now I'm just like OK, just let it go, breathe and enjoy."

We're secretly kinda bummed that it won't be on the show, so we can't wait to see the photos!

On Friday Ben Affleck and his youngest daughter Seraphina stopped by Brentwood Country Mart, and if we had to guess, we'd say these two were planning something special for Jennifer Garner this Sunday!

Ben is back in town after spending a few weeks in Detroit shooting Batman vs. Superman, but unfortunately for Jen, it looks like filming will be going a little longer than expected on the superhero flick.

Last week Entertainment Weekly reported that the shooting schedule for Batman "has forced a delay" in Ben's upcoming Prohibition-era crime drama Live by Night because Warner Bros moved the Batman release date from summer 2015 to May 6, 2016.

Hmm, that's not exactly good news!

Emma Roberts jetted out of Los Angeles International Airport on Friday afternoon with fiance Evan Peters, and the paps had the balls to ask her who was a better kisser: her beau or Palo Alto co-star James Franco!

Emma grabbed her bags at the curb and politely ignored the question, but we are curious to know what she thinks of James, especially in the light of recent events. You know, all his semi-naked selfies and how he tried to seduce a 17-year-old girl on Instagram? And let's not forget about that never ending rumor that he boned Lindsay Lohan...

Wonder if Emma got along with James or if she was just as creeped out as we are these days?

We almost didn't even recognize Teri Hatcher! And it's probably been a while since she's had the paparazzi snap her picture, so she was caught off guard too!

On Friday Teri grabbed coffee in Studio City, and after Desperate Housewives ended, we haven't really been paying much attention to the 49-year-old actress. Maybe she needs to go make out with Ryan Seacrest again? We're totally kidding, but we still can't believe that happened back in 2006...

So has Teri been dating anyone since then? Last we checked she was still single, but she chatted with the Mirror last year and revealed that she's ready to find love again. “I have been really fortunate to have some great experiences in my life, and I look forward to more, and I would really like to have someone special to share those with. I guess that’s what I’m looking for," she said. “My daughter is older and it feels like there is more energy right now to be available. So it will probably happen.”

Awww!

Jennifer Aniston attended the Living Proof Style Lab event in Boston on Friday, and the 45-year-old actress showed off her sleek bob as she posed for photos with CEO Jill Beraud and the company's other partners, Jon Flint and Bob Langer.

Jen is a co-owner and spokesperson for Living Proof hair care, and Beraud said in a statement, “Jennifer embodies everything we stand for – a unique combination of beauty and brains. She not only has the most fabulous hair but is an amazing creative talent, and has shown she is a savvy businesswoman with a serious interest in developing small, innovative companies.”

Jen, who became famous for her hair back in the 90s with her "Rachel" 'do on Friends, added, "What caught my attention about Living Proof is the company’s unique approach to hair care – using scientific technologies to offer women actual proof in a bottle rather than hoping for results. Over the years, my hair has been subjected to everything...blow dryers, flatirons, curling irons, color, extensions, you name it. After using these products, I felt like I finally discovered a solution that works every day."

And it certainly looks like it! Maybe we should switch over too...

Zoe Saldana and husband Marco Perego arrived at LAX on Friday night, and we swear, we only see this couple at the airport! Zoe attended the Whitney Art Party in New York City the previous night, and prior to that she was at the Met Gala.

Though Zoe was slammed for her poufy Met Ball dress, what really made the headlines this week was when she chatted with Sirius radio and revealed one of the craziest places she's had sex.

“I am part of the mile high club," she said. "OK this is ghetto, but I’m from Queens, so whatever. There is a train from like Coney Island all the way back into the city, and it was between two train cars. It was super-ghetto."

Super ghetto, but who knew?!

Gwen Stefani, her three sons and their nanny drove out to Palm Springs on Friday, and the group will be spending Mother's Day weekend in the desert!

Gavin Rossdale wasn't spotted in the car with Gwen, so either he's already there or he'll be joining them later today. Looks like Gwen, who gave birth to baby Apollo a little over two months ago, is going to take it easy by the pool and maybe get pampered with a spa treatment. We're sure a certain someone planned that for her!
