Robert Wagner Celebrates His Granddaughter’s 13th Birthday in Sweet Post

The decorated veteran actor took to Instagram to share a heartfelt message in honor of his granddaughter entering her teen years. Last week, he also celebrated his 35th anniversary with his wife.

On Sunday, June 1, Robert Wagner posted a sweet photo of himself beaming alongside the young girl, who also smiled shyly at the camera.

"Happy 13th birthday to my beautiful granddaughter, Clover. Watching you grow into such a smart, kind, and spirited young lady has been one of life's greatest joys," he captioned the post.

"Grandma and I are so proud of you and the young woman you're becoming. Welcome to your teenage years—this is just the beginning of a wonderful journey. We love you so much," he continued.

Robert then tagged Clover's parents, his daughter Natasha Gregson Wagner and her husband, Barry Watson. Natasha is the late Natalie Wood's first daughter with film producer Richard Gregson.

Natalie married Robert twice, first in 1957 and again in 1972. The former couple also had a daughter, Courtney Wagner, in 1974. Natalie tragically passed away in 1981. Nine years later, Robert married Jill St. John in 1990.

The "Hart to Hart" star celebrated their 35th wedding anniversary last Monday, May 27, sharing a slideshow of their best memories on Instagram. "35 years of love, laughter, and partnership with my beautiful Jill. Every day by your side has been a blessing. Happy Anniversary, my love 💕🍾," he wrote.
