The 43-year-old actor -- who stars in the historic drama -- admitted to ET's Carly Steel that he was thrilled to see that Cher made it out to the event. "It would have to be Cher," Bale said when asked who he was most pumped to see at the premiere. "[My mother-in-law] was very excited to see Cher."
The Oscar winner is also a big fan of Star Wars, and while his 'Promise' co-star, Oscar Isaac, has a role in Star Wars: The Last Jedi, Bale said he got zero insider information about the highly anticipated movie while on set with him. "He was very tight-lipped about that because I'm a real Star Wars fan," he said. "I've still got all the figures from when I was a kid and everything like that. ...He wasn't having it."
The Promise hits theaters on April 21.
Bale wasn't the only one excited to see Cher at the premiere. Orlando Bloom as well as Kim and Kourtney Kardashian posed with the 70-year-old "Turn Back Time" singer, and ET chatted with the icon about Kim mimicking her hairstyle. Check it out:
