The spin-off will be launched by Suits' season 7 finale, which is also functioning as a backdoor pilot.
"The contracts of all Suits original cast members are up after Season 7, so both Adams and Markle will have fulfilled their current obligations", according to the site.
Markle plays Rachel Zane, a former paralegal who is now a lawyer and engaged to Mike, which might make a dual departure easier to plot.
Adams, 36, is set on exploring other career options, but won't shut the door on returning next season as a guest or recurring character, according to The Hollywood Reporter. The show will return for the second half of its seventh season next year.
Reps for Adams and the network declined to comment on the report; however, a source tells EW that discussions are still ongoing.
So. can Harvey, Donna and Louis go it alone in Season 8?
Adams and Markle aren't the first regulars to leave Suits. Do they move to Chicago to join Gina Torres's Jessica in her spinoff series?
Markle has made headlines during the past year for her off-screen romantic involvement with Britain's Prince Harry. "I'm going to let what happens happens and hope it all works out".
Per a new report from Deadline, Meghan Markle and Patrick J. Adams are both likely to leave the show after Season 7.
