A former “American Idol” contestant charged with raping a minor creepily fronted a band called Sexual Harassment after he was booted from the reality show — twice. Randy Madden, 45, started the presciently named group after he failed to gain a single “yes” from the “American Idol” judges in 2008 when he tried to wow them with a performance of Bon Jovi’s “Livin’ on a Prayer,” which Simon Cowell savagely cut off after about 20 seconds. Madden was arrested by the Ventura County Sheriff on Nov. 3 with unlawful sexual intercourse with a person under 18, and oral copulation, anal and genital penetration by a foreign object, People reported. His charges also included sending harmful matter and luring and dissuading a witness from reporting a crime.
