( CNN ) -- The world of social media burst with excitement Friday as millions took to Twitter , Facebook and other sites to join a virtual wedding party for Prince William and Catherine , Duchess of Cambridge . At the peak , there were 300 tweets per second using the Royal Wedding hashtag , according to Tweetminster , a news platform which monitors activity on Twitter . As Catherine stepped out of her car for the ceremony , nearly 9.4 % of all tweets worldwide mentioned the word `` wedding , '' according to Trendistic , which also monitors Twitter trends . `` I wish Kate & Willem the very best in their marriage ! : ) , '' Mark Kwakernaak of Rotterdam in the Netherlands posted on Twitter . For Americans , the royal nuptials meant a pre-dawn start to the day . For some , it conjured a bit of nostalgia . `` Yes , I set my alarm to wake up early to watch the # RoyalWedding , '' said Renee Nicole , who tweeted from northern Colorado . `` I remember watching Prince Charles & Princess Diana 's wedding , with my Mom . '' Much of the Internet buzz surrounded what gown Catherine would wear down the aisle . `` I just ca n't wait to see the DRESS ! '' Stephanie Golangelo tweeted from Cleveland . `` More than anything , I wan na see Kate 's dress ! '' echoed Mary Pranica of Minneapolis . Celebrities also joined in the online excitement . Victoria Beckham , a guest at the wedding with her footballer husband David , wrote on Twitter Thursday night : `` London looks beautiful ! ! ! We are so proud to be British ! '' `` London 's looking delightful today ! Flags at the ready ! '' wrote Harry Potter actor Tom Felton . Television personality Joan Rivers joked : `` I just read that the Royal Wedding is likely to have 2 billion viewers ! Many of them will be air-traffic controllers watching at work . '' British celebrity chef Jamie Oliver wrote : `` Royal wedding day ! ! national day off ! ! have a great day today guys , I hope it includes family , friends , bad dancing food and a little drink . '' Former Spice Girl Mel B -- now living in Los Angeles -- said she was `` getting sooo excited about the wedding , up at 5am to comment about it . '' `` Wake up Kath-eters ! '' comedienne Kathy Griffin wrote . `` Wan na hear ur thoughts on all things royal wedding . '' `` Congrats to William and Kate ... and Kate 's sister , '' wrote Justin Bieber , who is currently on tour in Sydney , Australia . The wedding proved to be a bit of downer for those thinking they had a shot at one of the world 's most eligible bachelors , while others decided to look at the bright side . `` Ladies , CALM DOWN u can still MARRY HARRY : ) , '' Aditya Pratama of Jakarta , Indonesia , said on Twitter . Lauren Demitry of Buffalo , New York , took a similar approach . `` That 's okay . I rather marry Harry anyways , '' she said . While the Twitter feed for the royal wedding surged with dozens of comments a minute , not all of them were -- shall we say -- for family reading . `` Who gives a damn about the # RoyalWedding seriously ? '' was a frequently repeated post that can be shared . Many marveled at the universal appeal of the event held at Westminster Abbey . `` Even my brother is keeping up with the # RoyalWedding more than me , '' tweeted Liana Borja of Guam . As the wedding drew near , a `` Runaway Bride '' theme appeared . In the 1999 movie , starring Julia Roberts and Richard Gere , a woman left a string of fiances at the alter . `` Speak now or forever hold your peace ... 'Kate , damn it - run ! ' '' Jo Garfein of northern California suggested on Twitter . `` Now THAT would make the # RoyalWedding more interesting . ''
