IT’S going to get a whole lot co zier on “Desperate House wives.”

Lovestruck 40-somethings Katherine and Mike (Dana Delany and James Denton), are moving in together, according to Entertainment Weekly.

The pair, whose little fling has blossomed into a full-on romance, will live in Katherine’s Wisteria Lane abode – which also happens to be Mike’s old house.

“Fans of the show since the beginning will remember that Mike used to live in the house that I live in now, so it is a sort of homecoming for him,” Delany says.

But Mike’s ex, Susan (Teri Hatcher), and Dave (Neil McDonough) are far from happy with the arrangement – as the move complicates Dave’s plan to destroy Mike.

“Like all things on Wisteria Lane, it will have its own set of challenges,” says Delany. “We aren’t going to be living in complete bliss. Susan has issues, for one. And Dave is still around trying to get revenge.”
