John Travolta celebrates son Benjamin's 11th birthday: 'My beautiful boy'

John Travolta shared a sweet message for his son Benjamin's 11th birthday.

"Happy birthday my beautiful boy. Your dad adores you!" the "Grease" actor, 67, wrote on Instagram Tuesday alongside a photo of himself with Benjamin and Ella, his daughter.

In addition to commenting on her father's post, Ella, 21, also shared an Instagram shout-out in honor of her little brother's special day, writing, "Happy Birthday Benjamin! The sweetest boy I know. You continue to teach me so much and brighten our lives. I love you!"

Benjamin and Ella are just two of the children Travolta shared with his late wife Kelly Preston, who died of breast cancer in July 2020. Their son Jett died in January 2009.

In a recent conversation with Kevin Hart, Travolta opened up about Benjamin grappling with his mother's death.

"He said to me once, 'Because mom passed away, I'm afraid you're going to,'" Travolta recalled. "I said, 'Well, it's a very different thing.' And I went through the differences about my longevity and her limited life."

Travolta then told Benjamin that "nobody knows when they're gonna go or when they're going to stay," referencing how Jett died at 16 and Preston died at 57.

"I could die tomorrow. You could. I mean, anybody can," he continued. "So let's look at life ... it's part of life, you see? You don't know exactly. You just do your best at trying to live the longest you can."
