Porsha Williams is packing her bags for Real Housewives Ultimate Girls Trip, PEOPLE can exclusively reveal.

The Real Housewives of Atlanta alum, 41, is joining the upcoming third installment of the popular Peacock franchise, according to sources. The show is set to begin filming July 18 in Thailand.

She'll replace Tinsley Mortimer in the cast, who insiders say chose to exit production for "personal reasons."

Williams first joined RHOA in season 5, and remained on the show through the end of season 13. She later appeared on her spinoff, Porsha's Family Matters.

Other cast members include Real Housewives of Salt Lake City's Heather Gay and Whitney Rose; Real Housewives of Miami's Alexia Nepola and Marysol Patton; and Real Housewives of New York City alum Leah McSweeney.

It's not yet known what the Thailand trip will entail — other than plenty of Bravolebrities building (and breaking) bonds, of course.

The first season of Ultimate Girls Trip premiered in November 2021 and featured Real Housewives of New Jersey sister-in-laws Teresa Giudice and Melissa Gorga; Real Housewives of Beverly Hills star Kyle Richards; RHOA's Kenya Moore and Cynthia Bailey; and RHONY O.G.'s Luann de Lesseps and Ramona Singer — all enjoying a getaway in the Turks and Caicos Islands.
