Dorinda Medley and Vicki Gunvalson are coming back for more reality TV … we’re told they’re starring in an ultimate ‘Real Housewives’ mash-up series.

Sources with direct knowledge tell TMZ … filming is set to begin in the next several weeks, and Dorinda and Vicki will be part of the all-star cast.

Remember … Dorinda announced her departure from ‘RHONY’ after 6 seasons last August, and Vicki left ‘RHOC’ in 2020 after 14 years on the show … so their time away from TV was short-lived.

The upcoming ‘Real Housewives’ show will stream on Peacock and we’re told locations are still being worked out. Peacock recently filmed a similar Housewives All-Stars series down in beautiful Turks and Caicos.

Waiting for your permission to load the Instagram Media.

Cynthia Bailey, Luann de Lesseps, Melissa Gorga, Teresa Guidice, Kenya Moore, Kyle Richards, and Ramona Singer made up the cast … and now we know at least 2 of the ladies for the upcoming Housewives mash-up.

Stay tuned …
