Who's In: Lady Gaga will star in her very first TV series regular role alongside Matt Bomer (White Collar) and Cheyenne Jackson (30 Rock). While the newly engaged, Sound of Music-singing superstar first announced the news of her casting on Twitter, Bomer and Jackson revealed their involvement when they joined the AHS: Freak Show cast on stage at their PaleyFest panel in Los Angeles on March 15.
Jackson and Gaga are both AHS newcomers, but Bomer appeared in one episode of AHS: Freak Show as a gorgeous, blue-eyed hustler who fell victim to murderer Dandy (Finn Wittrock). Jackson isn't a stranger to the Murphy universe, however -- he played Vocal Adrenaline coach Dustin Goolsby on Glee.
