Billy Corgan and Tila Tequila
Things Billy Corgan is famous for: being the front-man of alternative rock band Smashing Pumpkins and living with Courtney Love. Things Tila Tequila is famous for: making a sex tape with two female porn stars, being engaged to heiress Casey Johnson, hosting her own dating show, and probably her most important accomplishment to date, becoming the most popular artist on MySpace. Notice any crossover between these two? No? Neither did they, as it turns out. Their relationship was one and done.
