Turns out Cordelia from Oxygen's Bad Girls Club had a porn done under the name Nikki Carlisle. You can actually still watch it online, but I won't link to it, because I don't want to expose you tender souls, I'll just link to a place that links to it ;)

The Bad Girls Club is some reality show on Oxygen where "bad girls" deal with their "badness" or something like that - never watched it really. Cordelia, aka Nikki Carlisle actually has a blog on the show's website.
