At first we questioned the decision to cast Ashton Kutcher as Steve Jobs in the upcoming Jobs biopic, but after getting a closer look at the 35-year-old actor in character, we're totally buying it!

A new three-minute featurette has hit the web, and not only do we get to see more clips from the film, which hits theaters on August 16, but Ashton chats about how he nailed the role and spent countless hours studying the mannerisms and vocal inflections of the late Apple co-founder.

"It terrified me, and most of the great things I've been able to accomplish in my life were things that terrified me," he said during a recent interview with On The Verge. Click the video above to check it out!

She lightened her brunette locks a little bit back in March, and now Sofia Vergara has gone all the way ... back to her natural hair color! On Wednesday the Modern Family hottie stepped out in Brentwood for lunch at Tavern, and she showed off her newly dyed blonde tresses.

Back in 2010, Sofia told Self Magazine:

"I'm a natural blonde, but when I started acting, I would go to auditions, and they didn't know where to put me because I was voluptuous and had the accent -- but I had blonde hair. The moment I dyed my hair dark, it was, 'Oh, she's the hot Latin girl.' I loved it. I'd always felt a little 'too much' as a blonde, like a big-mouth version of Pamela Anderson. Being brunette toned me down a bit."

But now that she's snagged a role on a hit show and built up a fashion empire (seriously, she's raking in the dough from her K-Mart collection), she can do whatever she wants. And she looks hot, so why not?

Yesterday the news broke that Simon Cowell had fathered a child with Lauren Silverman, the wife of his former best friend, Andrew, and now it's been revealed that Andrew Silverman named Cowell in his divorce papers!

Silverman filed the legal documents in New York City two weeks ago, and he cited adultery and named Cowell as a co-respondent. This means Cowell could be called in as a witness and forced to reveal details his affair with Lauren, and he may even have to disclose financial information.

"It's really a signal to the spouse who cheated that the wronged spouse is very angry and that it's going to be a very nasty, scorched-earth, high-profile litigation," divorce attorney Martha Cohen Stine told the New York Post. Maybe Simon can lend Lauren some money? He's worth an estimated $320 million...

The papers cite sources who claim Andrew and Lauren "weren't estranged" when Lauren began her relationship with the music mogul, and it even seems like there was something going on when we snapped the three on vacation in St. Barth back in January of 2012.

Andrew's brother, Alexander Silverman, tells the Post, "It is an unbelievable story of betrayal. It is a sad story and a tragic story."

Wonder how much it's going to cost Simon ... and Lauren?

We love that Katherine Heigl is always in such a good mood!

On Wednesday afternoon the former Grey's Anatomy star and her mom stopped by the newsstand in Hollywood, and Kat stocked up on several fashion magazines, including the latest issue of Vogue.

Her sense of style has always been a little on the conservative side, so maybe she's looking to spice things up a bit? It seemed like just a year or so ago she was wearing frumpy sweaters and boring boots, but yesterday she wore a pair of skinny jeans and sky high blue heels. That's a huge improvement if you ask us!

Matt Damon stopped by The Late Show With David Letterman on Wednesday evening, and before slipping into a suit and tie, the 42-year-old actor posed for photos in a Boston Celtics tee. Take that, Lakers fans!

Matt is currently promoting his new sci fi action flick Elysium, in which he plays a factory worker who takes on a mission to hijack his way onto a man-made space habitat. So how did he get into such amazing shape for the role?

"It was really hard because I love to eat and drink!" Damon told People on Tuesday at a screening. "It's very hard to motivate me to get in shape." What did his wife think of his ripped physique? "I think she likes the variety," he said with a laugh. "When I did The Informant, I put on 40 lbs. and I was like, 'You kind of like this guy too?' I'm trying to talk her into [liking] that guy because that's the guy I'm most comfortable being."

Um, don't get too happy with the extra weight Matty!

Courtney Stodden made an appearance on Hollywood Blvd in a lettuce bikini on Wednesday to shoot a PSA for PETA, and it looks like the animal rights organization made the right choice in hiring her!

Courtney tweeted, "Had so much fun at @peta's Veggie Dog Giveaway event today. Honored to be apart of the fam & to spread awareness. #LettuceLady @pinkshotdogs."

The 18-year-old teen bride helped hand out veggie dogs and she chatted with fans and passers by about the benefits of becoming a vegetarian. While her heart was definitely in the right place, we have a feeling many of the folks she was chatting with were mesmerized by her recent breast augmentation rather than the perks of cutting meat out of their diets...

Like mother like daughter!

Kourtney Kardashian stepped out to run errands with daughter Penelope today, and the girls wore matching floral patterns for summer! Also, how cute is Penny's head piece?!

The mother-of-two looked a little tired, but can you blame her? She runs multiple clothing stores, endorses millions of product lines, films her reality show, and still has little ones to chase after!

If you believe the rumors, the brunette beauty might be getting yet another visit from the stork!

According to OK! magazine, the E! starlet has confessed to close pals that she's expecting her third child with boyfriend Scott Disick.

"She's very excited and only telling a select few right now - but she just couldn't keep it quiet any longer," a source dished to the mag.

It won't be long before all the Kardashian kiddies get their own spinoff!

Wearing berry-colored pants, Jennifer Garner was spotted running errands on Wednesday -- and the mom-of-three looks like she couldn't be happier! With her wet hair and casual attire, we just love seeing how down to earth Jen is!

While out and about, the 13 Going on 30 actress ran into some friends and stopped for a chat. We aren't going to lie -- we think if we met Jen we'd totally be BFFs.

Ben Affleck's wifey has been laying low this summer, but in December we'll see her back on the big screen with her Ghosts of Girlfriends past co-star Matthew McConaughey in the drama Dallas Buyers Club.
