After Olivia Wilde's O.C. appearance established her as "the actress you hire to have lesbian sex scenes midway through a TV drama's run," she's found her unique wares haven't gone over as well at House.

Wilde joined the medical drama at the beginning of last season as the bisexual internist nicknamed "Thirteen," whose affliction of Huntington's Disease quickly became a major ongoing storyline. Sadly, House producers were unaware of a simple fact of television fandom: if you give a beautiful new actress screen time at the expense of good-looking men who are already on your show, unholy hellfire will rain down upon you from the highest summits of the Television Without Pity messageboards. At least, that's our interpretation of Thirteen's rocky reception—Wilde has a different one:

Olivia Wilde thinks she knows the real reason her numerically-monikered House alter ego elicits such a negative reaction from some fans. "I think it's because she had a gay sex scene [this season]," she confesses. "I've got to be honest with you, I think that's what it is."

Could be! Perhaps, though, viewers simply thought the sex scene was superfluous and would have preferred a plot where Thirteen's same-sex loving resulted in a misdiagnosed case of Lesbian Bed Death, only to see her social life saved at the last minute when House swooped in with the real cause of the problem: Fangirlus Misogynoccus.
