Nearly two billion people tuned in to see Prince William and Kate Middleton tie the knot, including some of Hollywood's biggest stars!
What did domestic diva Martha Stewart, 69, think of the romantic ceremony?
"The trees in the aisle were the perfect touch, and the landau in which they are riding is amazing with one rider and four horses. The cavalry guard is beautiful, the horses are frisky and the tack? Fantastic," she tweeted. "The bride's mother looks radiant, as does father. The bride's sister did a spectacular job! Good luck to this newly wedded couple."
British pop star Natasha Bedingfield, 29, was equally impressed with the decor. "Love that the Abbey looks like Lord of the Rings with the trees inside!" she told her nearly 100,000 Twitter followers.
Former Spice Girl Emma Bunton, 35, summed up her thoughts with a simple tweet: "Absolutely beautiful couple! They look exquisite!"
"I'm so happy for William and Catherine," Real Housewives of New York City star LuAnn de Lesseps, 45, announced. "Catherine's dress was amazingly beautiful and the ceremony. . .wow!"
90210 costars Shenae Grimes, 21, and Jessica Lowndes, 22, also used the social networking site to share their two cents.
"Kate Middleton looked absolutely stunning in McQueen by Sarah Burton, as did her beautiful sister Pippa," Grimes wrote. "Well done, ladies!"
"Weddings make me emotional," Lowndes added. "All this orchestra music makes me want to go to Disneyland. . .Is that weird?"
