Julia Fox shared a set of rare throwback pics on Instagram today.

The actress celebrated her son’s first birthday — posting his pics and writing a heartfelt message.

In the caption, she wrote: “My beautiful baby is 1 today!! Thank you so much for showing me what love is. Thank you for humbling me and teaching me patience and hard work."

Fox added: “Thank you for being my biggest blessing. My greatest accomplishment. My masterpiece.”

She also noted: “I don’t deserve you but somehow we’re here and I promise to love you unconditionally and accept you for who you are.”

The photos also showed her ex Peter Artemiev.

Not long ago, Fox ranted about her baby daddy on social media.

However, she apologized to him through her podcast.

She said: “All I want to say is, I’m sorry. You’re not a deadbeat, I know that you’re not, and I know that it wasn’t that you weren’t trying to see [son] Valentino, it’s that you weren’t trying to see me.”
