Kate Hudson took full advantage of Throwback Thursday on Aug. 11 when she took to Instagram to share a very old, very epic family photo. In the snap, a young Kate poses with her family, including mum Goldie Hawn, stepdad Kurt Russell — whom she calls "Pa" — and a few of her siblings. She captioned it simply, "OG Squad." The group, who is all dressed in amazing '80s gear (Kurt's sunglasses are the best), smile for the camera in front of a beautiful backdrop. If we didn't know any better, this could easily pass as a scene from Chevy Chase's National Lampoon's Vacation.
