The actress announced she was quitting the legal drama shortly after getting engaged to Prince Harry.
Meghan Markle is set to appear in her final episode of US TV show Suits.
The 36-year-old – who once revealed she’d love a job in breakfast telly – announced she was quitting the legal drama last year, shortly after getting engaged to Prince Harry.
Her last scenes are in the finale of the seventh series, which will air in America on Wednesday.
The special two-hour episode will see Meghan’s character Rachel Zane finally tie the knot with Mike Ross (Patrick J Adams).
A teaser video on Suits’ Instagram page shows Rachel and Mike holding hands at the altar on their wedding day, under a sea of fairy lights.
“After seven seasons, the moment has finally arrived. Don’t miss #MikeAndRachel say “I do” in the two-episode season finale,” the caption says.
Ms Markle, who has played Rachel in the show since 2011, confirmed in her first joint television interview with Prince Harry at the end of last year that she would be giving up her acting career.
“I don’t see it as giving anything up, I just see it as a change,” she said.
Early in 2018 actor Adams announced he was also exiting the popular series.
