“How to Teach Filthy Rich Girls” is the catchy name of the TV pilot. Sounds like a perfect fit for the CW, right after “Gossip Girl.” According to the Hollywood Reporter, the drama centers on a Yale-educated young woman who is hired to be the tutor to two rich heiresses in Palm Beach. The show is from top writer-producer Rina Mimoun, who has worked on “Everwood,” “Dawson’s Creek,” “Gilmore Girls,” and “Pushing Daisies.”
