Markle, 36, is said to have been prompted to make this career move following reports that she and Prince Harry are set to get engaged before Christmas this year.
A source told The Daily Star: “Meghan knows she can’t really act at the same time as being a princess and is happy to make this career sacrifice."
“She really enjoys her charity work with Unicef and will broaden out her charity commitments when she becomes a full-time royal.”
The insider added that the couple plan to announce their engagement by the end of this year.
This comes after reports that Markle had decided not to sign up for another series, with another source telling The Sun: “Meghan loved playing Rachel and feels she owes so much to Suits.
“But Harry can’t move to Toronto, so she’ll have to move eventually if they want to be together.
“Her decision to give up the biggest role of her career would mean a lot.”
Markle has been based in Toronto as the legal drama which has grown to be one of the most popular shows on our screens is set in Canada.
While it hasn't been confirmed yet, we're sure Markle's fans will miss her loveable, resilient and kind character on the series.
