John Travolta’s daughter Ella Bleu is mourning the death of her mother Kelly Preston. The 20-year-old actress took to social media after her mom’s passing on Sunday to pen an emotional tribute. “I have never met anyone as courageous, strong, beautiful and loving as you,” Ella began. “Anyone who is lucky enough to have known you or to have ever been in your presence will agree that you have a glow and a light that never ceases to shine and that makes anyone around you feel instantly happy. Thank you for being there for me no matter what.”

Ella continued, “Thank you for your love. Thank you for your help and thank you for making this world a better place. You have made life so beautiful and I know you will continue to do so always. I love you so much mama.❤️”

John shared Ella, as well as nine-year-old son Benjamin with Kelly. The Gotti stars’ firstborn son Jett died in 2009 at age 16. The Grease actor confirmed his wife of nearly 29 years’ passing on July 13 with a heartbreaking social media post. “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,” John wrote. “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,” John added. “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.”

Kelly died on Sunday, July 12, after privately battling breast cancer for two years. She was 57. “Choosing to keep her fight private, she had been undergoing medical treatment for some time, supported by her closest family and friends,” a representative for the Travolta family told People magazine. ”She was a bright, beautiful and loving soul who cared deeply about others and who brought life to everything she touched. Her family asks for your understanding of their need for privacy at this time.”
