Melanie, 57, and Kris, 59, also got in on the bikini action, the Keeping Up with the Kardashians matriarch looking chic in black, with Melanie rocking a more colorful halter top.
Melanie and Kris also took to their Instagrams to gush about their friendship while on vacation.
"Sunset vibes with @melanie_griffith57 #amazing #blessed #beautiful #friendship," Kris wrote alongside her selfie of the two, while Melanie snapped a solo photo of Kris, calling her "my beautiful friend."
Perhaps the recent trip was prompted by all three ladies' reported single status? Griffith split from Antonio Banderas last June, and there are rumors that Kris has recently split from boyfriend Corey Gamble. As for Dakota, Us Weekly reported that she and her ex, British musician Matthew Hitt, split over the holidays.
