Sporting a grungy plaid buttondown shirt with rolled-up jean shorts and sandals, Mary-Kate Olsen was spotted out running errands in Hollywood on Wednesday (August 27).

Per the usual, the 22-year-old twin mogul tried to hide her face from the camera while she walked back to her car following a quick stop at a local shop.

Looking sexy in a multi-colored dress, Rihanna was spotted enjoying the Los Angeles nightlife with a few gal pals on Tuesday evening (August 26).

The Grammy-winning “Take A Bow” singer hopped out of the passenger seat of her friend’s ride - heading into the trendy Villa Lounge while making sure that she was all covered up as paparazzi snapped away.

MacKenzie Phillips was arrested earlier today (August 27) at LAX International Airport for alleged possession of crack cocaine and heroin, breaking reports tell. 

The actress, 48, has had a long battle with drug addiction, which is what led to her termination from the show One Day At A Time. During her arrest, Phillips was allegedly carrying the drugs in balloons and baggies.

We've been seeing a lot of Katie Holmes rehearsing for her Broadway debut (there she is today in the pix above, and she's not wearing jeans!) in NYC recently. The thespian even went out last night to take in a performance of August: Osage County... But where was Suri? Back at home? Actually, after the fam spent the weekend together, we think Tom returned to LA on Monday, the 25th, with Suri... leaving Katie solo in New York to focus on her theatre work. He probably knows she needs to concentrate - and he's probably been missing his daughter a whole lot, too! Let's hope they all reunite soon!

Taking full advantage of the beautiful southern California weather earlier today, Hilary Duff was spotted out and about all by her lonesome.

The “So Yesterday” songstress donned a beige striped tank top layered over a white tank top with a pair of jeans and sneakers as she made her way to a friend’s house.

Here's the father of six, looking dapper in his tux at the Burn After Reading premiere at the Venice Film Festival... And here he is earlier in slightly more casual attire. But still smokin' hot, right? Which look do you like better? We'll take Brad any way we can get him!

If you love actor Matthew McConaughey… wait until you get a load of his mom, Kay McConaughey. In her newly released book titled “I Amaze Myself”, Kay dishes on all sorts of topics - touching on everything from where Matthew was conceived to how her husband passed away while making love to her.

Kay told press that having Matthew was not planned, but a pleasant surprise. “I was deciding, ‘Do I want to have another baby? Do I want to have an affair? Or go back to school?’ That’s when Matthew was conceived. We had tried for 16 years and no baby. So Matthew was a big surprise!”

Check out our second-favorite Spice Girl Mel B. out with her hot(?) hubby in Hollywood last night... Pink is a hot color, but is it right for Scary? Hey, the woman can rock any color, right?

Looks like Zac Efron's got some lessons to learn about driving - not to mention manners! The teen heartthrob accidentally ran over the foot of one of our paps on his way out of a parking lot last night. Of course, we can understand that accidents happen - but we can't understand why Zac would take off without even checking to see if the poor guy was okay! C'mon, Zac - what kind of example is this kind of behavior setting for all your young fans? WTF, Zac?

Our photographers caught MMA superstar Quinton "Rampage" Jackson pouring out some Grey Goose while partying at the Mirage in Vegas. We just hope Quinton wasn't driving - he's had enough problems behind the wheel lately even while sober! Hey, Rampage might be facing three years in the slammer for his vehicular misadventures - he's probably going to be partying every chance he gets in case it turns out to be his last chance!

After a rousing arrival via luxury boat earlier today for their photo call, Brad Pitt and George Clooney traded in their suits for tuxedos on their way to the 2008 Venice Film Festival premiere of “Burn After Reading.”

The “Oceans Eleven” co-stars were accompanied by directors Ethan and Joel Coen, as well as co-stars Frances McDormand and Tilda Swinton to the Sala Grande.

With the impending Presidential Election getting closer and closer, our favorite celebrities are stepping up to support their choice for President of the United States.  And Eva Longoria was busy showing her support for the Democratic Party yesterday (August 26).

The “Over Her Dead Body” hottie was spotted dropping into the MySpace Café in the Corner Office Restaurant in Denver, Colorado, and her Presidential preference was clear.

Tara Reid has joined the countless other celebs who "design" their own clothes, and she debuted her new fashion line, Mantra, at the Christian Audigier trade show in Las Vegas yesterday. Mantra features beach and casual wear for consumers who like overpriced outfits with lots of colorful beadwork. “It’s about putting into the universe what you want in life: Red means love, pink is friendship, green is lucky, black is protection," Tara said in a statement. "You’re gonna have a story when you wear this bikini or when you put this dress on: You’ll either get love or meet a new friend or you might meet a guy.” Or someone is going to laugh at you, take your picture and send it to Glamour magazine for their "Fashion Don'ts" column! Tara continues, “I feel like I’m in a really great place in my life, and I love what I’m doing. I love acting but I can’t hire myself. If this works, then we’re in business. If not, I tried.” Indeed. I do have to give credit to Tara for being original - at least she didn't copy Heidi Montag's hookerwear or Lindsay Lohan kneepad leggings (which could also be considered hookerwear). However, it looks like the model is thinking the same thing I am - why did Tara string a bunch of raver bracelets onto a backless t-shirt and decide to stick a $65-$180 price tag on it? I'm confused. So very confused. What do you think of Tara's clothes?
