Robert Wagner is honoring his daughter, Natasha Gregson Wagner, by sharing a rare photo together.

The actor, 96, uploaded the post via his Instagram to celebrate Natasha’s 56th birthday.

“Please join me in wishing a very Happy Birthday to my wonderful daughter, Natasha. Jill and I are so proud of the woman you are and the joy, laughter, and love you bring into our lives. We love you and wish you the happiest of birthdays 💕 @ngdubdubs,” Robert captioned the snap.

Natasha was born to Natalie Wood and Richard Gregson in 1970. The West Side Story star was married to Gregson from 1969 to 1972. She was also married to Robert from 1957 to 1962, and after her divorce from Gregson, she married Robert a second time in 1972.

Wood welcomed her second daughter, Courtney Wagner, in 1974. Courtney was Wood’s first child with Robert.

After Wood died in a tragic drowning in 1981, Robert legally adopted Natasha. Robert, who also is a father to daughter Katie, 62, from his second marriage to Marion Marshall, is currently married to Jill St. John. They tied the knot in 1990.

Though Robert is not Natasha’s biological father, the pair maintained a close bond after Wood’s tragic death.

“I was so lucky I had two dads who were deeply committed to raising me and helping me through,” Natasha told People in April 2016. “They were trying to pick up the pieces for us and stumble forward and find out what our life looked like after that.”

She continued, “I’m certain because my mom died, my relationship with my stepdad is way deeper than it would have been had she lived, because he had to be my mom and dad.”

To celebrate Robert’s 96th birthday in February, Natasha shared a touching post via her Instagram.

“My dad is 96 today. I’ve been so lucky to have him by my side all these years,” she wrote at the time. “He is young at heart and older than I ever imagined he would be! Full of wisdom, love and good cheer. He’s funny as hell and as good as they get.”

In April, Robert shared another rare glimpse of the extended family — including his granddaughter Clover — in an Instagram post commemorating the 52nd birthday of Natasha’s husband, Barry Watson.

“Join Jill and I in wishing our terrific son-in-law Barry Watson a Happy Birthday 🎉 Always fun times when you’re around-grateful for the laughs, the love and these unforgettable moments together,” Wagner wrote alongside a photo of himself, Watson and granddaughter Clover. “Cheers to another great year ahead!🎉 @realbarrywatson.”
