Think American Idol is a family-friendly program? Think again. Yesterday — less than one week after Cowell & Co., crowned a top 13 for the first time in Idol history — the show’s producers scrambled to find a new call-in number after discovering that 1-866-IDOLS-13, the intended number for the 13th contestant, was actually…(wait for it) a sex line. Sure, this would be perfect if Bikini Girl (real name: Katrina Darrell, pictured) was still in the competition, but will the special, one-time-only, inconsistent number bode well for the contestant awarded the coveted pimp spot? Or will dialing confusion hurt their chances (if we see Danny, Adam or Lil in any other slot tonight, I think we can assume that the producers are worried about the latter)? Either way, you’ve got to give it up to a phone sex company with the brains to choose a number that takes advantage of clumsy Idol fans, no?
