At 77, Goldie Hawn looks amazing – and after the ever-youthful Hollywood icon shared a new video on Instagram, fans were all focused on just one thing.

Wearing her famous blonde hair down to her shoulders, and rocking her signature smoky eye makeup, the First Wives Club star sported a “Be Kind to Your Mind” t-shirt – sales of which benefit the MindUp charity, part of the Goldie Hawn Foundation – for the video.

“Ok, this is my new t-shirt: ‘Be kind to your mind’,” the proud grandmother, who has previously shared her own battle with depression, begins. “And it’s really important because our mindset is everything. It’s how we go through the day, it’s how we watch our mind, and how we care for it.”

In the clip, mental health advocate Goldie goes on to share her four steps to “a happier brain” – and among them is to smile.

“Remember that even if you don’t feel like it, smile,” says the Oscar winner in the clip. “Right? Because when you smile your brain smiles, too… What’s going on in your brain when you smile even though you don’t feel like it? It thinks it’s really a happier brain and we wanna get a happy brain!”

Comments on the advice immediately flooded in, with scores of fans telling Goldie how much she makes them smile.

“Goldie, your smile always makes my mind feel happy and makes me smile!! Thanks for this morning’s message, blessings and health and happiness to you and everyone!” said one fan.

“I needed this message more than anything today! I’m smiling right now and it feels so good!” wrote one, while another said, “Thank you for this wonderful advice. You make people smile.”

Even Goldie’s famous friends chimed in, like Ali Wentworth who revealed: “Well, when I see your face – I smile! And that smile makes me feel better!”

Oliver and Kate Hudson’s famous mom certainly knows a thing about smiling! Her smile became positively iconic when she first got her start on 1960s TV comedy show Laugh-In, and she has been keeping us all in stitches with her movies and bubbly persona ever since.
