John Travolta shares rare throwback photo of his two "babies" daughter Ella and son Benjamin

It looks like John Travolta is reminiscing about days gone by with his family.

Just weeks after celebrating his late wife Kelly Preston's birthday with a photo from 1991 of the couple on their wedding day, the beloved Grease star has now shared a sweet throwback photo of his daughter Ella, now 20, and son Benjamin, now nine.

In the rare photo, a young Ella can be seen subtly smiling at the camera as she holds her baby brother.

The 66-year-old actor simply captioned the post: "TBT 'My babies.'"

Unfortunately, not seen in the snap was their brother Jett, who tragically died in January 2009 after suffering a seizure.

Kelly passed away in July after privately battling breast cancer for the last two years.

John wrote an emotional post on Instagram on July 13, confirming that his wife of 28 years had died.

"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."

The family throwback photo also comes just one month after John's nephew, Sam Travolta Jr., passed away.
