Designer Nate Berkus, who was featured on "Oprah" last season, is being groomed to host a new daytime show for Winfrey's production company, Harpo, according to Broadcasting & Cable — which reports that "Trading Spaces" host Paige Davis (search) could be part of the show.

Berkus and Davis were featured on "Oprah" last season redecorating Davis' New York apartment.

Rumors of a decorating show in the works were given credence last week when Winfrey re-upped her deal with King World through 2011.

Part of the deal to continue hosting "Oprah" is for Winfrey to develop other programming, according to B&C.

Two years ago, Winfrey launch "Dr. Phil" into syndication after years of being featured as a frequent Winfrey guest. McGraw is now the No. 2-ranked daytime show in syndication (airing here on Ch. 2), second only to Oprah herself.

Winfrey's company is notoriously tight-lipped about future plans.

"We have nothing to announce at this time," a Harpo spokeswoman told The Post yesterday.
