Kelly Preston's Scientology help

Kelly Preston admitted she may not have overcome the sudden death of her 16-year-old son Jett in 2009 had it not been for Scientology.

Kelly Preston counts Scientology as the main reason for overcoming the shock death of her son Jett.

The actress - who has been a Scientologist along with husband John Travolta for more than two decades - explained she might not have recovered from the sudden loss of the 16-year-old boy, who died from a seizure during a family holiday to the Bahamas in January 2009, had it not been for the religion.

When asked what got her through such a tough period in her life, she told Health magazine: "To be honest, [it was] the Scientology Centre. I don't know if I would have made it through without it.

"Don't sweat the small things. Love your kids like it could be the last moment."

The 48-year-old star - who shares daughter Ella Bleu, 11, with John - explained it was a "wonderful" moment when she found out she was pregnant with the couple's third child Benjamin Hunter Kaleo, who was born in November 2010.

She added: "We [had been trying] for quite a few years. When I found out I was pregnant, I was floored. I'd snuck out of bed and then came back and woke Johnny up in bed. We both started crying. It was wonderful."
