Salma Hayek shared a powerful Instagram post on Tuesday while showing a glimpse of her daughter. The 54-year-old is relatively private when it comes to her personal life so although she included her 12-year-old daughter, Valentina, in this photo, fans didn’t get to see much too much of her.

Hayek’s post was about climate change and her wanting to take a stand against it. The photo is of Hayek and her daughter’s hands making a pinky promise. The caption read, “It is in my maternal instinct to dream for my children the best future I can possibly give them, but with the worsening of environmental conditions, I worry what kind of world my children and my grandchildren will inherit. Stand with me in the fight against climate change. Let’s make a pinky promise to our children to do our best for the environment and #VoteLikeAMadre November 3rd. @jlo, @evamendes let’s make a difference!”

The Mexican actress shares Valentina with her husbandFrancois-Henri Pinault and the couple has been married since 2009. Hayek, Pinault, and their daughter have been vacationing in Greece recently, but it seems that Hayek isn’t letting a family getaway get in the way of bringing awareness to something that’s important to her.

In addition to using Instagram to stand up against climate change and urging her fans to vote, Hayek has been sharing photos of herself enjoying the relaxing trip, including some bikini shots prior to her 54th birthday, which happens to be today.

One photo, in particular, was of Hayek looking stunning in a black one-piece bathing suit and a large hat. She captioned the photo, “Guess who’s turning 54 tomorrow? By the way, this is not a Throwback Thursday! Thank you Marjo for turning into a photographer during the vacation!”

Then this morning, the “Like a Boss” actress posted another photo of her in a yellow cut-out bathing suit with a matching yellow skirt having a blast celebrating her birthday in Greece. She wrote, “I am very grateful and proud for every single one of my 54 years. Thank you for all the birthday wishes, especially to my fans who made a special account for my birthday. What a gift! @salmahappybirthday ✨”

Happy birthday Salma!
