JJ Abrams photobombs ABC7's Periscope stream at Star Wars Celebration!

ANAHEIM, Calif. -- J.J. Abrams proved he's a master of the photobomb while at the Stars Wars Celebration convention Thursday when he sneaked into our Periscope live stream.

The director of the latest "Star Wars" reboot was spotted roaming the floor as was Walt Disney Co., CEO and chairman Bob Iger. Abrams even complimented our own Alysha Del Valle's hair do, which was inspired by Princess Leia.

From Wookiees to Clone Troopers, the four-day Star Wars Celebration honors all that the iconic film franchise has spawned over the past 38 years.

"Star Wars: Episode VII" is set to hit theaters on Dec. 18, 2015.
