Jennifer Aniston was feeling reflective on her 54th birthday.
The picture shows John Aniston holding a young Aniston as he poses with Dow at the beach.
"Thinking about these two humans that created me as I bask in the afterglow of a beautiful birthday," Aniston captioned the post.
"Thank you ALL for my beautiful birthday wishes. I felt sooooo much love from so many and ALL of it is going to carry me through this wild and beautifully unknown year ahead. I love you!" she said.
Model Naomi Campbell, comedian Chelsea Handler and actress Kate Hudson were among those to show love for Aniston in the comments."Happy Birthday, you beautiful tush!!! I'm glad you are surrounded by such love," Handler wrote.
Dow died at age 79 in 2016, while John Aniston died at age 89 in November. Aniston paid tribute to her dad on Instagram following his death.
Aniston is known for playing Rachel Green on Friends and now portrays Alex Levy on The Morning Show. She and Reese Witherspoon wrapped filming on The Morning Show Season 3 last week.
