Paul Giamatti has been getting strange calls from a pop superstar.

During a recent appearance on “The Howard Stern Show,” the Golden Globe-winning actor spoke about his experience playing phone tag with legendary singer Cher, telling host Howard Stern, “Every now and then I get a message from somebody that says Cher … really needs to talk to me, like it’s important, like it’s crucial that she talks to me.”

The actor explained he was confused to hear she was trying to get in touch with him, saying his reaction was “What the f—? Why does Cher want to talk to me?”

“I was flabbergasted. I’m still flabbergasted by it. I’m trying to take it in,” he said about finding out about his nomination. “I’m so happy the movie got acknowledged in so many ways. I’m so happy the editor, Kevin Tent, got acknowledged. He’s the best. I’m still just trying to take it in. It’s amazing. I didn’t need to call anybody. Everybody started calling me. I was like, ‘Holy cow.’ Everybody started contacting me. So, it was lovely.”
