Just three months after John Travolta's wife Kelly Preston passed away, the movie star is now grieving the passing of his nephew.

Sam Travolta, a screenwriter and the son of Travolta's brother Sam Snr, passed away on September 23rd in his home in Wisconsin, USA.

The cause of his death is not yet known, but Sam Jr's high school friend said that he would be "greatly missed, but he will always be with us."

"I found out through high school friends, they reached out to me to let me know. We had a great time when we used to hang together in high school," Mavrostomos said. "Sam was definitely proud of being related to John Travolta. He was happy-go-lucky and a good friend, good-spirited."

Sam Jr. spoke fondly of his relationship with his uncle claiming that Travolta would send him a monthly allowance.

 "I'm a struggling screenwriter living in a tiny one-bedroom apartment, so John's money helps," he told the National Enquirer in 2015.
