Speculation that Markle, an avid philanthropist who also has been with the series began almost immediately after she started dating Prince Harry in 2016.
Her departure opens the door for a potential royal wedding, which has been wildly speculated since the actress met Queen Elizabeth.
Adams and his fiancée, Troian Bellisario, gave fans a sweet glimpse into their Winter getaway, but that's not their only adorable social media moment.
The duo, who have been dating for four years and engaged since 2014, don't post pictures of themselves as a pair that frequently, but when they do it's worth the wait.
Reps for Adams, Markle, USA Network and producers Universal Cable Productions all declined comment.
