The 58-year-old actress -- who, if you didn't know, is mother to Fifty Shades star Dakota Johnson -- showed off her banging bikini body in a sexy, patterned two-piece while lounging poolside at the Hotel Rodavento in Valle de Bravo, Mexico.
Griffith recently posted an unfiltered selfie and challenged haters to "say some mean things" about her. But when you look this good, what mean things can you say?!
Griffith was vacationing in Meixco for Eva Longoria's wedding to Jose Baston. The Working Girl star was one of a handful of celebs on the star-studded guest list, which also included Victoria and David Beckham, Longoria's Desperate Housewives co-star Felicity Huffman and Katy Perry.

My Mai Tai is as big as my head. This one is for my Grandmother Sugarplum who loved her "high tides" whenever she was in Hawaii. I think she would have loved this one.

She takes #BAYWATCH to another level.. World fell in love with @alexannadaddario in #SanAndreas and I was so impressed by her chops and presence every day, that I had to have her "rep the squad" in our film. Just wait til you see her - and all our girls - kick ass and protect the bay. #GameOver #BaywatchBabes #CoverYourEyesBoys #BAYWATCH SUMMER 2017.

Left my phone behind to be present! I am so grateful for the people I've met this year but more importantly for the people who have been consistent and by my side through thick and thin. That'd be YOU. Thank you for another year! Love you guys!
