Born Kelly Kamalelehua Smith in Honolulu, Preston studied acting at the University of Southern California before landing some bit parts on television including “CHiPs” and “Roseanne.”

That led to the role of playing Mary Lee on the short-lived television series “For Love and Honor.”
But Hollywood took notice in 1988 when she starred as Marnie Mason, Arnold Schwarzenegger’s character’s love interest in the comedy “Twins,” a film which also co-starred Danny DeVito.
That same year she met Travolta during a screen test for the film “The Experts.”

The actress had not been photographed publicly at a major event since June 2018 when she walked the red carpet with her husband for the premiere of his film “Gotti” in which he portrayed the late mobster, John Gotti and she played his wife, Victoria Gotti.

John Travolta posted this on his Twitter Account along with a photo of his beautiful wife:
It is with a very heavy heart that I inform you that my beautiful wife Kelly has lost her two-year battle with breast cancer. She fought a courageous fight with the love and support of so many.  My family and I will forever be grateful to her doctors and nurses at MD Anderson Cancer Center, all the medical centers that have helped, as well as her many friends and loved ones who have been by her side. Kelly’s love and life will always be remembered. 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
