Those that follow legal drama Suits will know Prince Harry's future wife far better as Rachel Zane, paralegal and Mike Ross's (Patrick J. Adams) fiance.

Adams couldn't resist having his say on the engagement news of his friend and co-star yesterday, posting the below joke on Twitter:

Markle's on-screen father, actor Wendell Pierce, also took to Twitter following the news,

Both Markle and Adams are set to leave the legal drama after the seventh season, although the show will continue on without them. A source told US Weekly recently that Patrick "was always leaving the show. He made his mind up a while ago.

"They were waiting for Gabriel Macht [Harvey Specter] to sign. He’s going back so there will be a season 8 and as of now, 9."

Another source added that there will likely be a wedding between Mike and Rachel at some point in the second half of season seven that "will make it an easy break for Meghan to leave as well".
