American Idol co-host Brian Dunkleman went from being a living room fixture in millions of homes to begging fans to help launch his new TV show.

Dunkleman was Ryan Seacrest‘s sidekick when Idol debuted in 2002, but to his lasting regret, left the mega-hit show after the first season. Now he’s seeking a new gig – in a series about himself!  Title? American Dunkleman – natch!

"Let’s be honest – I didn’t think American Idol would be nearly this successful. Had I known, I would have stayed," he told The ENQUIRER exclusively.

After the 37-year-old entertainer announced his departure, Simon Cowell declared Dunkleman had "made the biggest mistake in the history of show business."

In his drive to return to the spotlight, Dunkleman, who’s found sporadic TV work, is opening up about his personal agony on Facebook – a site for social networking.

"I’m trying to get fans to support a new TV comedy series.

"The show is based on how every day of my life I’m reminded of the biggest mistake I’ve ever made – leaving Idol – and how I can’t go anywhere without being reminded of that career decision.

"I’m appealing to members of Facebook in an attempt to get one million fans to support the show before we pitch it to the networks."
