If there were an award for coolest mother-daughter duo, it would definitely go to Goldie Hawn and Kate Hudson [1]. On Tuesday night, Goldie and Kate attended Stella McCartney's Autumn collection event, and from the looks of it, they had an absolute blast. In addition to striking some silly poses together on the red carpet, the pair let loose inside when Stella's famous dad, Paul McCartney, took the stage for a surprise performance. Thankfully, Kate caught the fun moment on camera [2] and later shared it on Instagram. "Front row with... our parents 🙌🙏❤️ #WhatANight ✨," she captioned a clip of Goldie and Stella dancing in the crowd. Could this family be any cuter?
