I will be taking some time to be there for my children who have lost their mother, so forgive me in advance if you don’t hear from us for a while. But please know that I will feel your outpouring of love in the weeks and months ahead as we heal. All my love, JT."

JOHN TRAVOLTA SAYS HE'S LEARNED THAT ‘MOURNING IS SOMETHING PERSONAL’ AFTER LOSS OF WIFE KELLY PRESTON

The pair lost their son, Jett, in 2009 when he was 16 years old after he had a seizure while on vacation with his family in the Bahamas. 

In April, Travolta opened up about the grieving process to Esquire Spain.

"I learned that mourning someone, dealing with grief is something very personal," he admitted. "Mourning is individual and experiencing your own journey is what can lead you to heal. Your grief is different from another person's journey."

"The most important thing you can do to help another person when they are in mourning is allow them to live through it and not complicate it with yours," Travolta advised. "Even though it's great to have company, sometimes it turns into you helping them instead of you working on your loss and grief."
