Actress Kate Hudson wrote a poem about her star mother Goldie Hawn's life on her 70th birthday.

In honour of Hawn's 70th birthday on Saturday, Hudson shared a video on Instagram that first pans across cupcakes and a "Happy Birthday" banner on a plane and then shows her cuddling in her mother's lap and planting a kiss on Hawn's cheek.

Throughout the video, Ellie Goulding's new song "Army" plays, reports people.com.

The "Rock the Kasbah" actress captioned the video with an original poem.

"On this day in the clouds I'm sure. A man had a plan for the twenty first. He took a sweet soul and said it's time my dear. You must go back down to share your cheer. Your beauty will please."

"Your laughter will spread. You may even meet a man and be thirty years unwed. To many you will be their rising muse. And light will bathe you in golden hues. So, with excitement she went back down to the earth."

"To meet her old friends, Laura Hawn to rebirth. She had no clue on that day what would be. And day by day it seemed god made her special in some way. She never seemed to follow in line."

"Always a bit on the outside, goofy by design. She danced her own beat. Played her own drum. Shook the worlds axis a bit being seemingly dumb. But dumb she was not. Smart as a whip."

"And her beauty was something many found hard to resist. But she had one desire that grew with the years. To be happy she says, to be happy without fear. People laughed in her face and said don't be so silly. But she paid no mind to those who could not see as clearly."

"She may not have remembered that day in the clouds. But her message is pure and of the touch of god. Find your joy she says, what brings you joy. Live fearlessly facing the sun."

"Bathe gently under the moon. Love all around you. Laugh till you cry. Cry till you laugh. We live till we die. She says live with all your might!"
