Video: John Travolta and Family Step Out

John Travolta, wife Kelly Preston and their daughter Ella Bleu took the stage at Disney's D23 Expo in Anaheim on Friday, making a rare public appearance following the loss of their son and brother, Jett Travolta.

The family stepped out to celebrate their upcoming comedy with Robin Williams, 'Old Dogs,' in theaters Nov. 25.

Sixteen-year-old Jett passed away suddenly from a seizure while the family was vacationing in the Bahamas last January. ET recently confirmed that Preston canceled a speaking engagement in which she was set to discuss the loss of her son.
