Eve Hewson is on the new Cinemax show “The Knick,” and while on The Tonight Show starring Jimmy Fallon, Hewson admitted she prank called Justin Timberlake!

Hewson is Bono's daughter. She explained to Fallon that when she was 11-years-old, she found phone numbers on her dad's home computer and "might have stole some numbers and pranked your boyfriend Justin Timberlake."

Hewson said she pranked a number of celebs, but Timberlake was the one who actually went along with it.

“We asked him general knowledge questions from the back of a cereal box,” recalled Hewson, noting, “He was getting the answers right, which is why he didn’t hang it up.”

Timberlake had no idea it was Hewson and her friends... until now!
