Patrick J. Adams, who plays Mike Ross in "Suits," is set to star opposite his real life fiancée in the second half of "Suits" Season 4. Troian Bellisario is guest starring in one of upcoming episodes. She is playing the character called Claire, a girl Mike dated in the past. Bellisario portrays the role of Spencer Hastings in ABC's "Pretty Little Liars."

Variety is reporting that Bellisario's character will make an appearance in a "flashback." Claire and Mike met when he was working as a bike messenger. It is likely that Mike met Claire after his break-up with Tess. Variety describes the character of Claire as someone who is an "idealistic law student and volunteer at a social services law clinic."

Mike and Claire's relationship gets complicated when Mike helps Claire with one of her cases. According to Variety, "the result causes him to question the trajectory of his life." It is likely that Bellisario will make an appearance in episode 13, as Aaron Korsh, creator of "Suits," has said on Twitter that Episode 13 of "Suits" Season 4 is a flashback episode. When someone asked on Twitter how long he has tried to get Troian to guest-star, Korsh said, "We'd discussed it. I waited for right role to emerge & hoped it worked out."

The first half of "Suits" Season 4 introduced several new characters, including Amy. She was Mike's secretary at the investment firm. When Mike got fired from his job as an investment banker, Amy disappeared from "Suits." Korsh has not ruled out the possibility of Amy making an appearance soon. He said on Twitter that he very much likes the character of Amy and that they have "definitely discussed" Amy's return.

Adams, 32, and Bellisario, 28, reportedly got engaged in early January this year, after three years of dating each other. The couple first met when they were doing a play together in 2009. On the show, Adam's character is dating Rachel Zane.

"Suits" Season 4 is expected to return in January 2014, with six remaining episodes.
