Kristen Stewart stood out in a gorgeous blue Stella McCartney dress and matching Barbara Bui heels on the Kids' Choice Awards orange carpet in LA this afternoon. She stopped to sign autographs for some fans on her way into the show, where she is up for favorite movie actress. Kristen is kicking off promotional work for Snow White and the Huntsman, though this nomination is primarily for her work in the Twilight series. Kristen stars in one of two adaptations of the classic fairy tale hitting the big screen this year, and we took a look at Snow White's transformation into a badass through the years. Kristen is also reportedly headed to Cannes next month to premiere On the Road, so it should be an exciting few months of red-carpet appearances for Miss Stewart.

Cute couple Emma Stone and Andrew Garfield posed together on the orange carpet at the Nick Kids' Choice Awards in LA on Saturday. The real-life loves and The Amazing Spider-Man costars looked adorable making their first official red-carpet appearance together. Recently the two have been cozying up in NYC, where Andrew is starring in the Broadway production of Death of a Salesman. Emma cheered him on from the front row at his first performance, and since then she and Andrew have been spotted around Manhattan holding hands and checking out the city. They got all dressed up — she in Antonio Berardi and he in a dapper burgundy suit — for this evening's show, where they both are presenting.

Selena is nominated for both favorite TV actress and favorite female singer at this year's Kids' Choice Awards. Selena was sporting a fresh tan from her work on the set of Spring Breakers, the movie she's been shooting for the past few weeks.

Sienna Miller and Tom Sturridge sat outside for a lunch in London's Soho neighborhood. The couple managed to sneak in some PDA while tucking into a meal with two male pals. Sienna covered her baby bump in a loose-fitting denim top, which she paired with leggings. Sienna's among the many pregnant celebrities at the moment, as it emerged in January that she and Tom are expecting a child. Sienna spoke to British Vogue about their plans for a family: "I'm in my second trimester, so I'm I-can-talk-about-it pregnant, even though I'm under strict instructions not to say anything." It's a particularly exciting time for Tom, who's also got a huge movie on the way. His On the Road will be out this Summer, and is rumored to be making a big debut at the Cannes Film Festival in May.

Orlando Bloom gave 1-year-old son Flynn Bloom a lift yesterday while out for a walk in the hills of LA. The father-son duo were out enjoying the afternoon with Orlando's dog Sidi. Earlier this week, Orlando logged some time with his guy friends. Orlando and Justin Theroux took their motorcycles out for a spin and grabbed lunch at Gjelina.

Orlando and Flynn had fun together while mom Miranda Kerr made the press rounds on behalf of Victoria's Secret. The trio will likely be together this evening, though, for a special environmental event. Miranda Kerr's focusing on Earth Hour, a consciousness-raising event in which participants will turn off their lights for one hour starting at 8:30 p.m. tonight.

Stars embraced the Spring weather and enjoyed the outdoors over the last seven days. Victoria's Secret Angels Miranda Kerr and Candice Swanepoel debuted a new bikini collection in LA, while pregnant Uma Thurman wore a two-piece in St. Barts. Jessica Simpson walked down the aisle at a friend's Palm Springs wedding, and Jennifer Lawrence took The Hunger Games to Spain. All that and more happened — click through to see the hot pictures.

Michael Bublé and his wife Luisana Lopilato touched down in Rio yesterday evening. The couple are just one country away from her native Argentina, where Michael and Luisana celebrated one of their many huge wedding celebrations last year. The couple tied the knot exactly one year ago today in Buenos Aires!

Their trip to Brazil comes during an exciting professional time for Michael. He was just nominated for a Sony Radio Academy Award in the category of best music program, having hosted a two-month-long show for a London network last year. He's also in the running for four honors during Canada's Juno Awards, which take place tomorrow. Michael won't attend, however, as he's due to perform twice this weekend in Rio and Sao Paulo.

March means award season is over, but this month still brought the first day of Spring and a whole host of celebrity fun! There were plenty of hot red carpets to watch, with Jennifer Lawrence and the Hunger Games cast promoting their movie around the globe and 21 Jump Street's Channing Tatum and Jonah Hill cracking up the country. Kristen Stewart and Charlize Theron started press for Snow White and the Huntsman while Kate Hudson showed off her bikini body on vacation in Mexico. Angelina Jolie took Shiloh and Zahara to Amsterdam, but that's not all that happened — click through to see this month's best pictures and biggest headlines!
