Mila Kunis

Mila Kunis stopped by Neil George Salon in Beverly Hills for a touch-up and then headed to Taco Bell for lunch yesterday. She's hanging on the West Coast while a few of her Oz the Great and Powerful costars traveled to promote their project. James Franco and Rachel Weisz landed in Tokyo today, and Michelle Williams made a stop by Good Morning America. Mila will make her own promotional appearance on Conan this Thursday.

The cast was together in LA last week, though, for the world premiere of their Disney movie. We chatted with Mila on the red carpet, which was swapped in for a yellow brick road, about keeping the secret of which witch turns green in the film from her family and friends. Viewers will get to see the result next month, when the classic tale hits the big screen on March 8.

The stars of Disney's Oz the Great and Powerful stepped out for the world premiere of their film last night in LA, and we were live on the scene to capture all the action on the red carpet. Michelle Williams, James Franco, and Rachel Weisz all attended, as did Mila Kunis, whose boyfriend, Ashton Kutcher, was also on hand for the debut.

James Franco arrived by hot air balloon in a plaid Gucci suit for the event, while Mila walked the "yellow brick road" clad in a cream-colored Dolce & Gabbana dress. Mila told us that this would be her first time seeing the film and that she doesn't get nervous having friends and family watching with her. Though Mila was able to keep some of the film's big secrets under wraps, her costar Rachel Weisz — who wore a stunning orange Victoria Beckham dress — wasn't as tight-lipped, saying, "I have told some friends, but they'll keep it hush hush."

Michelle Williams, who plays Glinda in the movie, wore a white beaded Prada dress on the red carpet and shared her excitement about getting to help design and pick out her character's costumes. While her boyfriend, Jason Segel, and her 7-year-old daughter, Matilda, weren't with her on the red carpet, Michelle told us that she was looking forward to showing the film to her little one in a less "overwhelming" setting. Oz the Great and Powerful hits theaters on March 8.

Ashton Kutcher and Mila Kunis brought their PDA courtside last night to watch as the LA Lakers took on the Phoenix Suns at the Staples Center. The usually press-shy couple cuddled up and laughed during the game, which the home team won 91-85. It wasn't all overt affection for Mila and Ashton, though — at one point, they held up a piece of paper to share a private moment. Their night out comes in the middle of a fun week. Ashton turned 35 on Feb. 7, and tomorrow is, of course, Valentine's Day. Tonight, Mila will attend the LA debut of Oz The Great and Powerful — and we'll be LIVE from the premiere! The fun starts tonight at 9:30 p.m. EST/6:30 p.m. PST right here on POPSUGAR. Ashton is expected to attend as well.

Ashton and Mila were joined at last night's matchup by Will Ferrell, who stole the show dressed as an usher with the name tag "Ted Vagina." Rocking his Anchorman 2 beard, Will made headlines by escorting Shaquille O'Neal out of the stadium after a supposed infraction from Shaq.

Mila Kunis sported a '60s-inspired look in a Fendi jumpsuit on the cover of Allure's March issue, which hits stands Feb. 19. Inside the magazine, the brunette beauty continued the theme, dressing up in a Paco Rabanne number and down in a Marc Jacobs t-shirt and briefs. Mila has been busy juggling several projects lately, including the highly anticipated Oz: The Great and Powerful, but she paused promotions to pose for the publication. She also opened up about her life as a single girl and shared her thoughts about onscreen nudity and losing weight for roles. Here's more from Mila Kunis in Allure:

• On being single: "For four years I was single. An amazing time. An amazing time. I love being single."
• On her nudity in Friends With Benefits: "I showed side boob. I don’t need to show ass. You get one or the other. You don’t get both."
• On weight loss for Black Swan: "Unfortunately, the only way I could play a ballerina was to look like a ballerina . . . fit and bony."
