There is nothing more precious than the bond we have with our best friend.

Sure, we've got loving spouses, supportive parents and even close sibling relationships, but there's something unique about the relationship we have with the pal we've known the longest.

It's a relationship that happens so naturally and we often take for granted that they will always be there. So when the day comes that they're not, we're utterly devastated.

Hollywood star Goldie Hawn knows how profound the loss can be. She recently shared a special message with her fans.

Goldie revealed that she is mourning the death of her best friend. Without going into the details of her loss, Hawn shared a beautiful picture in tribute to the woman she calls best friend.

She wrote a short message to her fans about the loss:

"My best friend has passed," the star announced on Sunday, beneath a vintage black and white photo of herself and the unnamed friend on Instagram.

"Please treasure each other," she wrote. "Best friends get us through. Blessings to all this Sunday."

In an adorable follow-up post, she shared a sweet photo of her 4-year-old granddaughter, Rio Hudson, hugging her own best friend.

She simply wrote: "Says it all!"

In an interview with PEOPLE, she spoke about the importance of friendship: "You have your girlfriends you really laugh with and there aren't that many."

Her secrets to a long-lasting relationship?

"Love, gratitude, compassion, because sometimes every man or every woman will drive their partner crazy. Family. Fun. Laughs. Sex," Hawn said. "If you don't nurture that, and remember, you're done."

Hug your best bud today and remind them just how special they are!
