Mila Kunis

This week, it's like all our favourite beauties got the memo to step it up a notch — everyone looked next-level amazing. It was hard work selecting only ten, but gosh, these ten are superb. Rihanna owned the red carpet at the Grammys with her beautiful curls and perfect skin, while Miley Cyrus' red-hot red lip at the Marc Jacobs show in New York had everyone talking for all the right reasons. Alexa Chung was understated and cool, with a bright pop to spice things up, and Olivia Palermo? Well, her hair's so perfectly shiny it's criminal. There's much more to see — just click through to check it all out!

Mila Kunis, Michelle Williams, and Rachel Weisz each brought her red carpet A game to yesterday's Oz the Great and Powerful premiere in Hollywood. Mila took a dramatic retro route in Dolce & Gabbana, Michelle stuck to her signature ladylike flair in a floral Prada sheath, and Rachel delivered gorgeous color in a curve-hugging Victoria Beckham gown. While we wait to see what these beautiful ladies will wear for their upcoming promotions, step inside to get a closer look at their stunning ensembles from the big premiere.

A yellow brick road stood in for the red carpet at the Oz the Great and Powerful premiere in LA, and Michelle Williams, Mila Kunis, and Rachel Weisz arrived looking like they'd stepped out of a fairy tale. Click through to see the top looks of the night!

The stars of Disney's Oz the Great and Powerful stepped out for the world premiere of their film yesterday 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-coloured 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 co-star 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 is out on March 7.

Ashton Kutcher and Mila Kunis brought their PDA courtside yesterday 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 today is Valentine's Day. Today, Mila will attend the LA premiere of Oz The Great and Powerful and Ashton is expected to attend as well.

Ashton and Mila were joined at last night's match-up 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.

Oz: The Great and Powerful hits cinemas next month and the leading ladies of the classic children's story reboot are promoting the project with US InStyle's March issue. Rachel Weisz, Mila Kunis and Michelle Williams posed together for a glamorous shot and spilled about filming and family. Michelle touched on life with boyfriend Jason Segel while Rachel shared her favourite part of working with Michelle. Mila, who has been sticking close to Ashton Kutcher, talked about her tricky costumes. Here's more from Michelle, Rachel and Mila in InStyle:

• Michelle on Jason: "He is nice . . . I didn't actually realise who he was before I started dating him. I mean, I saw the Muppets movie, and I thought, 'Oh, that's cute,' but the truth is I didn't realise he made a lot of very popular, funny movies or was on a TV show. But maybe more important, I didn't realise he was so tall. I thought, 'Hey, man, you're cramping my style!' I tried wearing wedge heels for a while to compensate, but it wasn't me and I just gave up."
• Rachel on the best part of filming: "Michelle's daughter and my son are about the same age, so they went to camp together, and we took them bowling. It was really fun for me and Michelle too, because you don't get that many mummy playdates in our business."
• Mila on her costumes: "I spent a lot of the shoot in a leather corset, wired up in a harness, and flying around in a costume that weighed 10 pounds. I hear some women enjoy wearing a corset, but tell them to try 17 hours of that and then get back to me."
