Not only was Salma perfectly comfortable with the greys she pointed them out to her 8.9 million followers and declared herself to be proud.
"Proud of my white hair," she wrote.
She then repeated the same statement but in her native Spanish.
The post very quickly went viral clocking up more than 400K likes and attracting almost 4500 comments, many which were from fellow celebrities.
"Gorgeous lady," wrote Jessica Simpson.
"You are stunning," posted Lenny Kravitz.
Her regular fans were thrilled also.
"I'm so proud of you," wrote one.
"You don't hesitate to show everyone who you really are. You're not trying to be perfect for everyone. I love you my angel. You're as beautiful as ever."
And we have to agree.
And just in case you still weren't across the fact that Salma is only getting better with age, here's a snapshot from her social media account showing her utterly killing it in a leopard print one-piece and retro sunnies.
Salma is 100 per cent hot and as grown-ups ourselves, we're loving it.
