Marcia Cross' role as Bree on "Desperate Housewives" has kept her plate full this season with Bree committing adultery with Susan's (Teri Hatcher) ex-husband Karl (Richard Burgi), stealing recipes from her new neighbor Angie (Drea de Mateo) -- and now she has a plane crash in her future. Buzz is that someone close to Bree could die -- possibly her husband Orson (Kyle MacLachlan) or her son Andrew (Shawn Pyfrom).

"I would be shot if I said too much about the upcoming episode with the plane crash," Marcia tells ET. "Sometimes [exec producer] Marc Cherry says way more than one could say, but since I don't know that, I am not going to divulge any secrets. There is a big plane crash and people do get hurt because they do in plane crashes, but I can't tell you more than that."

Marcia is also hoping to keep plates full this holiday season by partnering with Feeding America, the nation's leading domestic hunger-relief charity, and the Chinet brand in an online initiative called Grateful Platefuls. Through the program, Huhtamaki, makers of Chinet, will donate $100,000 to Feeding America, which will provide 700,000 meals to Americans at risk of hunger. Folks can participate at www.facebook.com/mychinet. All you have to do is log onto the site, write what you are grateful for and pick a plate to display to participate in the hunger-relief program.

"It is hard to pick a charity because there is so much need in so many ways," Marcia says. "I picked this one because it is a primal visceral thought of my husband or children or parents being hungry. I picked this because it is America's largest hunger-relief organization, and it is so simple to go online, put your name in and what you are grateful for. It is such an easy thing to do, I thought I had to show up and do that."

One thing that Marcia, the mom to fraternal twins Eden and Savannah who will turn three in February, will not show up for is the updated version of "Melrose Place."

"I have a very busy life," she points out. "So it is not even about what I would do on 'Melrose Place,' because I have already done every crazy thing imaginable as the whacked-out Kimberly, but I don't have a minute in my day left, so I don't have any plans now … unless they want to float me on a raft and let me take a nap in the infamous pool."

"Desperate Housewives" airs Sundays at 9 p.m. on ABC.
