It's been less than a month since it was announced that Lady Gaga would star in American Horror Story's fifth season, Hotel — and on Sunday night, we found out she'd be joined by White Collar star Matt Bomer.

Bomer, who had a small role in Season 4's Freak Show, surprised fans at the American Horror Story PaleyFest panel in Los Angeles on Sunday to make the announcement. "I love collaborating with Ryan Murphy," Bomer said. "I had the time of my life [on Freak Show] and he said, 'Great. Would you come do it next season?' And I said, 'Hell yeah."

Bomer would not confirm or deny whether he and Gaga's character have a romantic relationship. At the PaleyFest panel, Bomer was also joined by Cheyenne Jackson, who is joining Hotel as well.
