“#GoldenHour with the kiddos,” the Wild actress, 41, captioned the image with daughter Ava, 17, and sons Deacon, 13, and Tennessee, 4, during their beach holiday.
Over the weekend, Witherspoon and her family joined costar Laura Dern and her family on an island retreat to celebrate the finale of their hit HBO series, Big Little Lies.
Dern also posted some vacation photos via Instagram.
“So happy to be celebrating the finale of #biglittlelies with my family in paradise. Let me know what you think!!! (Thank you to my sister @reesewitherspoon for the hospitality),” the Big Little Lies star, 50, captioned the image with son Ellery, 15, and 12-year-old daughter Jaya.
And there were plenty of images of the BFFs enjoying the tropical getaway.
In fact, the good friends and costars watched the series finale of the HBO drama together.
“We were texting with the other girls. We FaceTimed with Shailene [Woodley] yesterday,” Dern told Vanity Fair. “We all remain close, and I can’t believe our very good fortune in finding each other and forming this friendship. … And we’re now getting to be together with our families, our children, on holiday while we happen to be watching the finale.
