Kate Middleton attended a friend's wedding in a familiar Topshop polka-dot dress on May 11. She was first spotted wearing the black and white look on her Warner Bros. studio tour back in April. This time, it was the perfect outfit for the Spring nuptials of Kate and Prince William's friends William van Cutsem and Rosie Keene, who tied the knot in Ewelme, England. William served as an usher at the ceremony while Kate's sister Pippa and brother James were also in attendance.

The wedding took place while Prince Harry was on his US tour, but now the young royal is back by his brother's side. The two made an official visit to Tidworth, England, yesterday to open four new Help For Heroes recovery centers, which serve wounded service personnel. Kate skipped this event, but that doesn't mean that she hasn't been keeping busy over the past week. Kate has reportedly been taking cooking classes with her new housekeeper, Antonella Fresolone, as she preps for the arrival of her first child. Kate's brother-in-law, Mike Tindall, says Kate is a natural mother, though she'll have plenty of help once the royal baby arrives.

Following Monday's historic tornado that devastated the Oklahoma City area, there has been an outpouring of support from public figures, celebrities, and everyday Americans. President Barack Obama addressed the nation from the White House Tuesday morning, expressing his severe concern and promising federal aid for the victims and families. As search and rescue teams scour the disaster grounds, celebrities have also been taking advantage of social media to share thoughts, prayers, and words of encouragement. Oklahoma natives Olivia Munn and Carrie Underwood gave personal accounts and hopes for fellow Oklahomans, as did Kristen Chenoweth, who also asked her followers to donate to the American Red Cross and Humane Society relief efforts. Click through to see how public figures and celebrities are coming together to support tornado victims.

Katie Holmes hopped in a fountain at Washington Square Park in NYC today to film scenes for Mania Days. Her costar Luke Kirby accompanied her on the fountain run, and the onscreen duo splashed around for the cameras before they dried off and Katie headed over to pose for pictures with two little girls.

Earlier in the day, Katie and Luke took to a park bench to shoot more personal scenes, in which they exchanged several laughs and held hands. This was not the first glance of costar chemistry, though, since last week Katie and Luke got close while filming in front of a church. Work on the romantic drama, which deals with two manic depressives who fall in love, began a few weeks ago but is not expected to hit theaters until late next year.

Alec Baldwin swept his pregnant wife, Hilaria Thomas, off her feet at the photocall for his latest film, Seduced and Abandoned, at the Cannes Film Festival today. The two are no strangers to the South of France as they both popped up at the festival together just last year. Their first trip to Cannes may have been on Alec's mind during this year's photocall as he took Hilaria in his arms to reenact a moment from the 2012 festival when he carried her up the steps of the Palais for the premiere of Moonrise Kingdom. Interestingly enough, the film that Alec is currently promoting is a comedic documentary that follows his experience at the festival that year. Check out Alec's 2012 Palais photo-op and more glamorous Cannes Film Festival moments from years past!
