The actress, who stars in the new HBO series Vinyl, talked about the boy's fondness for the pop star in an interview on The Ellen DeGeneres Show Thursday, Wilde's 32nd birthday.
"His love for Beyoncé has really hit a fever pitch and I approve of course, but it's intense," she said.
The actress said Otis even got to see his idol in person.
"Jason was at a Clippers game recently and had Otis there and Beyoncé walked in and was sitting like, very far away on the other side of the Staples Center, court side," Wilde said. "And Jason said, 'Otis do you see who that is?' And he sat up and he's like, 'Beyoncé, Beyoncé.' And he stood on Jason's knees and just started going, 'Beyoncé!' And all these people were like, 'What is this 2-year-old doing?' And, you know, maybe one day she'll hear him."
