The new three-part series – The Real Housewives of Cheshire: Christmas Cruising – will air on ITVBe and the ITV Hub from 5 December at 9pm.
Embarking on Royal Princess for their first-ever cruise together are Hanna Kinsella, Lauren Simon, Lystra Adams, Nicole Sealey, Rachel Lugo, Seema Malhotra and Sheena Lynch.
Viewers will see the group sail from San Francisco to Mexico, calling at Cabo San Lucas, Loreto and Mazatlan.
Eithne Williamson, vice-president Princess Cruises UK and Europe, said: "To have The Real Housewives of Cheshire onboard a Princess Cruises ship for their first-ever cruise together is extremely exciting.
"We cannot wait for viewers to see all the incredible moments the Housewives experienced as they sailed around the beautiful Mexican Riviera – from the extraordinary service they received onboard to the varied activities they enjoyed in each fabulous port."
