Ben Affleck drew a blank (space?) when he went on The Ellen DeGeneres Show and failed to name three Taylor Swift songs.

While promoting his upcoming film, Live By Night, Ben sat down with Ellen and opened up about what it's like to be a father to his 11-year-old daughter, Violet. The dad-of-three proudly boasted that he's an expert in all things pre-teen — adding that he's a big fan of Taylor!

"We go to Taylor Swift concerts, and that's my life," he said. "Taylor Swift is great, by the way, she’s a great role model.”

Later in the show, Ellen challenged Ben's pre-teen knowledge by asking him to name three of T.Swift's hits in five seconds or less. The actor hilariously fumbled through his answer.

"'1989,' 'I Still Love You,' the John Mayer thing … come on! She’s amazing," he said.

Did you hear that? It's the sound of Taylor Swift fans cringing everywhere. While the actor did correctly name Taylor's latest album 1989, he admitted to "blanking" on her songs.

“She’s amazing. I love Taylor Swift. I’m blanking.”

Looks like even A-list actors have their embarrassing dad moments!
