John Travolta's friends and co-stars Tim Allen and Forest Whitaker have sent personal condolence messages to the movie star and his wife Kelly Preston following the death of their son.

Teenager Jett Travolta died from a seizure at the family's Bahamas holiday home on Friday, and messages of support from celebrities like Tom Cruise and Oprah Winfrey have been pouring in over the weekend. And now Travolta's Wild Hogs co-star Allen and his Battlefield Earth co-star Whitaker have offered their thoughts.

Allen says, "We know how much they (Travolta and Preston) loved and adored Jett and words cannot express how sad we were to hear about his passing."

Meanwhile, Whitaker adds, "Our families have had a long loving friendship, and John and Kelly are amazing parents. We have watched each other's children grow and cannot imagine the loss of Jett. He was a bright and beautiful young man, and we are honoured to have known him."
