Spoiler alert: Read no further if you don't want to know what happens to some of the central characters on Desperate Housewives.

Marcia Cross, who plays domestic goddess Bree on the ABC US comedy-drama, told AP Radio a flash-forward narrative device will offer viewers a glimpse five years into the future of the lives of the Wisteria Lane gang.

Cross said her character makes "a big leap".

"She's gone out into the world, and she's become a bit of a success," the 46-year-old actress said.

When asked if that success has anything to do with the catering business Bree started with her neighbour Katherine (Dana Delany), Cross replied: "It does have to do with the business. Bree definitely has made a name for herself."

And Bree, the embodiment of preppy style, will change her look.

"Let's put it this way, the (hair) flip has died and I'm so happy about that," Cross said.

She also revealed Eva Longoria Parker's character, Gabrielle, "has had some children".

When asked what becomes of the troublesome Kayla (Rachel Fox), who is Tom's (Doug Savant) daughter, Cross said: "She hightails it out of town or is hightailed out of town."

The season finale of Desperate Housewives airs in the US on Sunday.
