"Suits" season 4 spoilers reveal that Patrick J. Adams' fiancée Troian Bellisario will amp up the series' powerhouse cast, as the "Pretty Little Liars" actress could not hide her excitement for the guest appearance.

According to the "Suits" season 4 spoilers from Variety magazine, Patrick J. Adams' fiancée Troian Bellisario will play Claire, described as "an idealistic law student and volunteer at a social services law clinic in the second half of season four."

"Adams' character, Mike, meets Claire in a flashback to his days as a bike messenger. Ultimately they begin dating, but things get complicated when Mike tries to help with one of Claire's cases," the magazine added about the said "Suits" season 4 spoilers. "The result causes him to question the trajectory of his life."

Claire is set to make an appearance "during the back six episodes for the fourth season," said Cartermatt in its "Suits" season 4 spoilers.

"There is no confirmed return date just yet, but it should be in either January or March. USA won't bring the show back at a time when it is jam-packed against a ton of other shows," it added.

Meanwhile, Patrick J. Adams fiancée Troian Bellisario showed just how excited she is to be guesting in the series as she wrote in her Twitter: "I've always had a secret crush on Mike Ross."

In his own Twitter account, creator Aaron Korsh dished about waiting a long time to cast the "Pretty Little Liars" actress: "We'd discussed it. I waited for right role to emerge & hoped it worked out."

Based on the initial reports, Claire would not play spoilers to the Mike and Rachel Romance, which is already on the mend following the whole debacle last season.

Rachel has been trying to regain the trust of Mike after her former lover, Logan, kissed her and she kissed him back. Not heeding the advice of Donna to just let it go, Rachel told Mike about the kiss which created a friction between them.
