She will play Samantha Wheeler, "a talented new partner at Pearson Specter Litt who challenges the status quo and will either become the firm's greatest ally... or most powerful enemy," according to the press release issued by USA Network.
"Joining 'Suits' was the perfect organic way to not only collaborate with an EP I admire deeply, but to also become part of a show and cast that I am an immense fan of. I have watched Suits from the very beginning and feel incredibly lucky to be the newest member of the Pearson Specter Litt family," Heigl said in a statement issued to Entertainment Weekly.
Heigl's casting comes a day after announcing that the legal drama had been renewed for an eighth season without series leads Patrick J Adams and Meghan Markle.
