More than six weeks after the Jan. 2 death of Jett Travolta, his heartbroken parents are still struggling to cope with their loss.
John Travolta, 55, and Kelly Preston, 46, along with their daughter Ella Bleu, 8, are "regrouping and pushing through the grieving process," a source tells PEOPLE in its new issue. "They are trying to grieve and return to some sort of normalcy for Ella.
"But life isn't normal without Jett."
The Travoltas have been lying low at their Ocala, Fla., home since the devastating death
of their only son at age 16. Adding to their pain is the ongoing criminal case
in the Bahamas, where prosecutors allege that a politician and a paramedic tried to extort $25 million from the Travoltas after Jett died while vacationing with his family there.
"They were so hurt by the moochers," says the source. "But things have calmed down. Every day it gets better."
