Alexis Arquette, sibling to David, Patricia & Rosanna, has allowed A&E Networks to document her impending sex change. Filming has been going on for more than a year now, following Arquette's initial therapy sessions and her first hormone injections. The project is said to culminate with Alexis' completed surgery to which she has recently received the go-ahead from psychiatrists. David, Patricia and Rosanna will all participate in the documentary along with sister-in-law Courteney Cox. Alexis will also be one of the houseguests for The Surreal Life 6, slated to air in January.
