John Travolta and Kelly Preston are showing their late son Jett some birthday love! On Tuesday, which would have been Jett's 28th birthday, both Travolta and Preston took to Instagram to post photos they'd taken with him. 

Jett tragically passed away in 2009 when he was just 16 years old during a family holiday in the Bahamas. After suffering a seizure at the Old Bahama Bay Hotel on Grand Bahama Island, the teen hit his head on a bathtub, which resulted in his untimely death.
