DeGeneres noted that Beatty's crush was "fruitless," to which Bening playfully replied, "I didn't want to share that with him."
The 58-year-old actress also dished on the couple's upcoming 25th wedding anniversary, revealing why her husband is better at buying presents.
"I'm easier to buy gifts for," she said, sharing that the first anniversary present that she received from Beatty was a "beautiful wishbone pin."
"Our house was damaged very badly in the ’94 [Northridge, California] earthquake, in fact it was destroyed, and I lost the pin," Bening recalled. "One day, maybe six years [later] I went back in the room where I knew the pin was, I opened the drawer and it was sitting there."
