Kirk Douglas turned 100 on Friday, and his day was filled with so much love that we could burst! The iconic actor, known for his role in Spartacus, got sweet birthday wishes from all of his family, including daughter-in-law Catherine Zeta-Jones and her children.

Zeta-Jones, who's married to actor and producer Michael Douglas, put together an amazing tribute video for "pappy." She shared the montage, which highlights some of Douglas's biggest career moments, on Instagram, writing, "Happy Birthday Kirk!"

She wasn't the only one to post sweet sentiments for the actor, though. Her 16-year-old son Dylan also shared a silly video of his grandfather on Instagram, writing, "Happy 100th Pappy love you with all my heart (I swear he's not crazy)." You have to watch the hilarious video!

Dylan's younger sister, 13-year-old Carys, also took to social media to express her love for her pappy. She shared a throwback pic of Douglas, and captioned it with "Who's that dashing guy? How old is he? Well that's my grandfather and today he is 100 years young. Pappy, you inspire me every single day. I love you and I'm so excited to see you on your special day."

Seriously, this family is so sweet it hurts!
