John Travolta's Son Makes an Adorable Cameo on the Late Show

John Travolta's son Benjamin got a last-minute case of stage fright when he attempted to join his dad on stage during his appearance on Late Show With David Letterman on Monday. After John explained to the host that Benjamin wanted to say hello, Dave told him to bring him out on stage. But when John's wife, Kelly Preston, brought the 4-year-old out for his big debut, Ben wiggled his way out of her arms and sprinted backstage. John then tried to get Ben to change his mind, but he firmly shouted, "No!" Watch the cute moment above, then look back at these cute photos of Ben from 2011.
