The Veep has the “Housewives” on the move!

Vice President Kamala Harris will be a guest on Sherri Shepherd’s daytime show, “Sherri,” on Wednesday, 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 the same studio.

“Their schedule 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 tells Page Six.

Shepherd’s show films in Manhattan’s Chelsea Studios on W. 26th St., which will be shut down for most of the day, we hear.

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 through.

“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 4a.m., and cannot leave their studio floor the entire time that the Vice President is scheduled to be in the building.

“A lot of time and scheduling goes into those reunion shows. So 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 [the] Secret Service pulls up.”

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

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

Street closures will start that morning as early as 8a.m., we’re told.

Bravo did not get back to us for comment.
