Markle herself, meanwhile, has been in a high-profile relationship with Prince Harry for more than a year, and recently met his grandmother, Queen Elizabeth.
Sources said that should the 36-year-old actor depart from the show as a series regular at the end of the current season, the door will remain open for him to recur or guest-star in Season 8.
Reports previously speculated she would not return to the cable series.
Rumours have growing steadily for months that 36-year-old, who has played a paralegal-turned-lawyer Rachel Zane on the popular series since 2011, will quit the show to move to the United Kingdom and announce her engagement to Prince Harry.
Both Adams, 36, and Markle, also 36, have been on the show since its premiere in 2011. Although there is no official renewal news on season 8 by USA Network, Markle and Adams may not reprise their roles, reported Deadline.
The network would not comment to USA TODAY on the potential departures of Markle and Adams. She loved being on the show, and we loved having her on the show, that's why we're doing the spinoff.
" I would never have guessed that she would want to leave early, but she did, and it ended up working out".
"I went to bed, and woke up in the morning and realized "Oh, yeah".
USA's Suits may be losing two of its stars, Patrick J. Adams and Meghan Markle. The series is now in production on the final episodes of season seven, expected to air in US early next year.
