It was a dance party over two months in the making.
"Dancing Man" Sean O'Brien became a viral sensation when he was bullied for his dancing skills at a club in March, and an Internet campaign was launched to bring out the London resident to Los Angeles for a very special dance party.
On Saturday, Cassandra Fairbanks, who initially found O'Brien through Twitter, and campaign co-organizer Hope Leigh followed through on their promise by throwing a big shindig in O'Brien's honor at the Avalon in Hollywood.
More than 1,000 people attended, including Monica Lewinsky, who has been very outspoken against cyber-bullying. What's more, she even brought O'Brien a foot massager so that he could recover from all that dancing!

Moby also followed through on his promise to perform at the event.
Former Fresh Prince of Bel Air actress Tatyana Ali and My Big Fat Fabulous Life's Whitney Thore were also there to lend their support and to help raise money for the Trevor Project as well as other anti-bullying charities.
And if you were not at the event, you can still see O'Brien bust a move. As Leigh sings in this music video for "Home to Me," the "Dance Free Movement" continues to inspire with the Dancing Man.

And while the dance party was only for a night, O'Brien was grateful for his time in Los Angeles and shared a heartwarming message. "To the Twitter world, thank you for being interested and making this what it is. So much good in the world, we sometimes forget," he wrote.
