Courtenay Semel, the 28-year-old daughter of former Yahoo CEO Terry Semel, first came to our attention after parlaying the bit of fame she acquired from appearing on short-lived E! series Filthy Rich: Cattle Drive into a brief, possibly Sapphic relationship with Lindsay Lohan. Lohan has since moved onto a full-fledged lesbian relationship with Samantha Ronson (or at least she's not denying that it's a full-fledged lesbian relationship), and Semel is now following suit: according to the New York Post, she's now dating Johnson & Johnson heiress Casey Johnson. "They are so happy and completely in love," a source tells the paper.

Johnson, for her part, has sufficient cause for opting to go the other way: two years ago, the 28-year-old accused her 56-year-old philanthropist aunt Libet Johnson of stealing her 38-year-old boyfriend. Semel, on the other hand, just seems interested in getting her name in the tabloids, and has (correctly) figured out that entering into a girl-on-girl relationship is the most efficient way of doing so these days. So now the two are canoodling at Paris Hilton's housewarming party and dining at the horrifically-overpriced Nello's. Everybody wins!
