USA's hit comedy TV series Psych is wasting no time gearing up for its eighth season, as it was just announced that it will be bringing in three brand new guest stars.

According to TVLine, Elementary's Vinnie Jones, New Girl's Kali Hawk and Wonder Years' Olivia D'Abo will all be coming on board the program in its upcoming installment.

Hawk is set to appear as a skillful private investigator whose case brings her directly to Shawn (James Roday) and Gus (Dule Hill). To top it off, the character will apparently have a charming effect on Gus.

D'Abo will be joining the show as a "master infiltrator" and confidante to a heinous British convict, which will be embodied by fellow guest star Jones.

Along with the three newly announced actors, Carly Elwes will be returning in his role as Pierre Despereaux, and Kristy Swanson will be back as Marlowe.

While Season 8 of Psych won't be airing until early 2014, a two-hour musical special will be gracing the small screen at some point during the fall. Be sure to keep checking back for more of the latest details on the popular TV series.
