'WING'-ING IT Could he BE any more obviously bucking for a second Emmy nomination? In an episode scheduled during November sweeps month, Matthew Perry will return to ''The West Wing'' as White House lawyer Joe Quincy, the role he played in two episodes this spring. Though the character landed Perry an Emmy nomination, he's something of a jinx for everyone else. On the day of Quincy's job interview, the White House was on lockdown because a shot was fired. On his first day at work, he inadvertently uncovered a scandal that led to the resignation of the Vice President. Now, in an episode called ''Separation of Powers,'' the Chief Justice of the Supreme Court falls ill, and Toby (Richard Schiff) asks Quincy, who once clerked for the jurist, to be the hatchet man and ask him to resign. Better keep Perry away from Martin Sheen's President Bartlet.
'MIX' MASTER In anticipation of the Oct. 22 debut of ''Mix It Up,'' her ''Trading Spaces''-type show on cable's WE, producer and serial remodeler Courteney Cox has been making the publicity rounds, granting interviews to everyone from USA Today to InStyle magazine, recycling some oft-told tales. Yes, the new show, in which designers help housemates with clashing styles find a happy medium, was inspired by the style clash she experienced when she and husband David Arquette moved in together. Yes, she has purchased, redecorated, and sold at a profit five houses (she's on Nos. 6 and 7 now). Yes, she really is best buds with Jennifer Aniston and Lisa Kudrow and will cry when ''Friends'' tapes its last episode in January. Yes, she really is like Monica -- not only is she a neat freak, but she's also aching to have a child.
This last point is perhaps a sore one with the 39-year-old actress, who has had several miscarriages. Nonetheless, she discusses it at length in an upcoming interview with ABC's Barbara Walters. ''I actually can get pregnant pretty easily,'' she tells Walters, but she says she undergoes testing to determine the viability of her eggs. ''We want to see if the egg is okay before I get pregnant again, because I don't want to lose any more. We don't want to take any more chances.'' Of in vitro fertilization, she says, ''It's a wonderful thing that people can do in this day and age. And I'm lucky enough to be able to afford to do it. But I think it's great. And I will do it again.'' She says she and Arquette would consider adoption, but only after trying a surrogate. ''I do want his genes,'' she says. She also praises her husband of four years for his supportive attitude. ''He's really great. He goes to every appointment with me,'' she says. ''And he gives me all my shots.'' If you still need to know more about Cox's hormones, you can catch the full interview on Friday's episode of ''20/20.''
