This week in the world of social media, celebrities kept busy sharing their personal pictures from just about every location you can think of. Lara Bingle took a fresh-faced selfie on a plane (and has never looked better, we might add), while Miranda Kerr jumped for joy during a visit to Sydney's Balmoral beach. Ricki-Lee Coulter had a New York moment in a yellow taxi, Delta Goodrem and Renee Bargh hung out together in Los Angeles and Johnny Ruffo copped a seriously unimpressed look from his co-star Samara Weaving. Stealing the spotlight from them all? Fifi Box, who shared an adorable picture of her week-old baby daughter Beatrix. Cute? You betcha. Click through to see all these pics and more!

Basketball's March Madness is in full swing in the US, and to celebrate the annual college basketball tournament, we're taking a look at all the celebs who cheer on their favourite teams courtside, as well as the cute couples showing PDA on the Kiss Cam. Whether it's Justin Timberlake and Jessica Biel rooting for the LA Lakers in the playoffs, Cameron Diaz catching a ball mid-game, or Ashton Kutcher and Mila Kunis laughing at themselves on the big screen, stars love to support their most-loved players from the sidelines. See the celebrities hanging out, drinking beer, and checking out the cheerleaders when you click through now.

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.

Ashton Kutcher and Mila Kunis went out to dinner in Rome on Friday night. They ventured to the Trastevere neighbourhood for a meal at Checchino Dal 1887 and seemed to have the whole place to themselves. Ashton even left with a decorative plate commemorating their visit. Ashton and Mila are enjoying an extended getaway together in Italy, where she's shooting The Third Person with director Paul Haggis and a long list of co-stars that includes Liam Neeson, Olivia Wilde and James Franco. Ashton ventured to Europe to spend time with Mila when she's not on set, and they've been spotted sampling many of the city's traditional restaurants together.

There were a few major events dominating the headlines this week: Superstorm Sandy, Halloween and the Melbourne Cup Carnival. While one of them (Sandy) kept a few events from going ahead — like Heidi Klum's annual Halloween bash — the other two certainly kept us on our toes when it came to keeping up to date with all the latest celeb happenings. Halloween brought out famous faces like Kayne & Kim, Kate Moss, Lara Bingle and more, while the Races saw people like Nicole Kidman, Jesinta Campbell and Kate Waterhouse hitting the town (and various best dressed lists). Think that's all? Oh, no — there were surprise visits to Sydney from a famous mum and daughter and a major British girl group, Kristen Stewart hung out (and looked a bit awkward) with an Aussie in Hollywood and Jennifer Aniston got all misty-eyed when Drew showed off pictures of her new bub. It's all in here, and more, so just click through the gallery to catch up on the week that was!

It was a bigger, and scarier, week than usual this time round in celeb land, and all your fave fashion and beauty stars were involved! Superstorm Sandy dominated the East Coast of the US, including events-hub New York, right smack-bang in the midst of Halloween preparations and excitement. While that stopped some from celebrating (Heidi Klum, for example), others made sure to keep up spirits by donning their best disguises — our favourites are Emma Roberts and Margherita Missoni, who went all out. Of course, down under, Halloween isn't quite as big a deal, so we had stars like Jen Hawkins, Ruby Rose and Jesinta Campbell filling our quota for glamorous parties and events to perve on. Best of all? We didn't even need to send a photographer — the thoughtful beauties did it all themselves!
