The Season 3 contestant won over the hearts of millions with his now iconic Idol audition where he sang the Ricky Martin hit, “She Bangs.”
His appearance came as a total shock to American Idol viewers.
“You know, it really is great to look back and celebrate all that’s gone on in this very studio over the past 20 years. I can’t help but feel that someone is missing the party,” Seacrest teased. “Someone who helped put this show on the map, dare I say, the legend, whose very name is synonymous with American Idol.”
Seacrest then introduced Hung to the stage for a performance of the viral hit.
“I think you know who I’m talking about, Ladies and Gentlemen, please welcome William Hung,” Seacrest said, as Idol judge Katy Perry freaked out saying, “Oh my God!”
Hung exploded onto the Idol stage with an energy-filled performance of the Martin tune.
Following Hung’s performance, he gave Idol viewers an update on what he’s been up to since the exiting the show.
He revealed to Seacrest that he is now a motivational speaker.
“I tell people, I believe everyone has a right to try something new without being judged or ridiculed.
