Kelly's comedic timing was much more respected by That '70s Show fans, but there is a general consensus that Moore is the more attractive one—the world's words, not ours. Now that the shallowness of that statement is out of the way, why did they replace Eric's promiscuous sister?
Rumor has it that Kelly had a drug problem and after five years it was agreed to let her go. Kelly herself has admitted that she had a drinking problem while on the show, and in 2010 was arrested for a DUI. Sadly, when we tried a google image search of her name, we don't see the gorgeous sister, but a really bad mug shot.
