‘Wives’ can’t share this Secret

VICE President Kamala Harris is set to be a guest on Sherri Shepherd’s daytime show today, and sources tell Page Six that the appearance is forcing Bravo to move up the production time for its “Real Housewives of Potomac” reunion, which is shooting at Chelsea Studios, the same as “Sherri.”

The schedule of the “Housewives” cast and crew “now has to be rearranged and pushed up to 4:30 in the morning. All of their food deliveries have to come before the street is totally blocked off by the Secret Service,” a source exclusively told Page Six.

We also hear that the street will have barricades, and those who reside or work on the block will have to go through metal detectors to get to their buildings.

“The whole block will be shut down, so there will be a lot of organized chaos because of Harris’ arrival, which could mean their breakfast and lunch could be cold,” huffed an insider.

With Secret Service overseeing security, we hear the “RHOP” cast must arrive at their reunion at 4 a.m., and cannot leave the studio floor the entire time that the veep is scheduled to be in the building.

“A lot of [preparation] and scheduling goes into those reunion shows,” we’re told. “The set decorations, time cards, flights, guest arrivals . . . have all been turned upside down. Those ladies are not known for their punctuality. So if they want to avoid any issues they better be in that studio before Secret Service pulls up.”

The cast of the Washington, DC-area Bravo series was already slated to film its reunion episode at the studio — on a stage previously occupied by the “Rachael Ray” show — before Harris’ appearance on “Sherri” was announced.

Shepherd will begin her show with Harris in front of a studio audience at 1:30 p.m., we hear, and the pol is expected to be gone from the building at 2:30, immediately after her segment wraps.

Street closures will start this morning as early as 8, we’re told.

Bravo did not get back to us for comment.
