Sylvester Stallone took to Instagram to celebrate his eldest daughter’s birthday.

“A VERY HAPPY BELATED BIRTHDAY TO MY VERY SPECIAL DAUGHTER, SOPHIA!!!” he captioned the post.

As part of the post, the actor posted several pictures of his daughter from over the years.

Some of the photos also featured his estranged wife, Jennifer Flavin, who filed for divorce from the actor earlier in the week.

Stallone and Flavin were married for 25 years.

Stallone and Flavin also share two other daughters, Scarlet, 20, and Sistine, 24.

In her filing, Flavin accused Stallone of dissipating the family’s assets.

Stallone was recently seen attending a screening of his latest film, “Samaritan.”

The actor is also set to star in a Paramount+ series, “Tulsa King.”
