It’s Christmas on Wisteria Lane but it’s not Santa who’s flying in. A plane crash destroys the holiday cheer — and somebody is going to die. ET’s Kevin Frazier is on the set with “Desperate Housewives” stars Eva Longoria Parker and Felicity Huffman to try to sleuth out who does not survive.

“They actually have a plane flying in and they’re going to wreck it,” Felicity tells Kevin. “I mean, it’s not going to be the ‘War of the Worlds,’ but it’ll be devastating nonetheless.”

Felicity adds that her first thought was she hoped she wasn’t under the plane, and Eva points out, “Everybody’s always on pins and needles on the mid-season episode, which this is, and the season finale because there’s always a death.”

So who will it be?

“Somebody is dying — somebody dear to our hearts. Somebody a lot of people have a crush on,” is all that Felicity will say.

“We have a list going in the makeup trailer of all the deaths [on the show] and it’s just pages and pages,” Eva says. “Even the dog. There’s a dog that died.”

The day that ET was on the set, Lynette (Huffman) puts her unborn babies’ lives in jeopardy as she runs to save one of Gaby’s (Parker) daughters, so it is possible that there is more than one casualty of the plane crash?

One person who is going to survive for sure is Gaby, as Eva reveals info on how her character changes after the crash: “Obviously, she reevaluates her friendships, specifically with Lynette and her kids. She’s going to have some fun stuff coming up with her kids. She’s always trying to define motherhood. For her it’s a hard job. I like the way she handles it with comedy, but I think she’s going to take a new approach to it.”

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