Dita Von Teese is the latest celebrity to befriend Sean O'Brien, aka "the Dancing Man," whose photo used to body-shame him went viral in March. She picked him up in her 1953 Caddie on Monday, and they went out to lunch. Shown: Von Teese at an Oscars event in 2015. Reuters

Sean O'Brien's post-body-shaming tour continues. The 46-year-old British financier who was shamed online earlier this year for being overweight and having the audacity to dance, was dancing again on Saturday -- at a huge party thrown in his honor by a group of women from Los Angeles who saw his picture online and befriended him. The theme? Anti-bullying.

“One of the worst things that ever happened to Sean turned out to be one of the best things,” singer and motivational speaker Andrew WK said at the event, reported Yahoo.

O'Brien and WK were joined at Avalon nightclub by Monica Lewinsky, Moby, who DJ'd the event, and Cassandra Fairbanks and friends, who were O'Brien's original champions. "I offer my dj services for free for #DancingMan #DancingManFound #FindDancingMan. No one should ever be ashamed about dancing," wrote Moby in March on Twitter. $40,000 was raised via GoFundMe to finance the party.

And although Pharrell couldn't make it, he tweeted his support.

O'Brien's saga started in February, when a photo taken of him dancing was posted on 4Chan -- followed by a photo of him looking dejected and crestfallen, because he noticed he was being laughed at and photographed. "Spotted this specimen trying to dance last week," reads the caption. "He stopped when he saw us laughing."

When Cassandra Fairbanks, a writer for The Free Thought Project in Los Angeles, saw it, she was upset O'Brien was body-shamed and bullied just for trying to have fun, so she rallied to find him and throw him a dance party. In less than a day and over 11,000 tweets later, according to Mashable, he was found and accepted the invitation.

O'Brien has become something of a cause celèbre for celebrities who want to make a point against bodyshaming, but also because he seems like such a good-natured guy. And now, many would call him a pretty lucky guy: In addition to dancing with Meghan Trainor on the "Today" show and throwing out the first pitch on Sunday at the L.A. Dodgers game, according to People, Dita Von Teese also picked him up in her 1953 Cadillac on Monday, and he bought her her favorite food for lunch: tacos.
