The couple attended the Hawn Foundation UK launch event hosted by Goldie Hawn at Annabels on March 7 in London.
Kate and Goldie look more like sisters than a mother-daughter pair, flashing those famous smiles and having a great time at the event.
Goldie’s manager Alan Nevins tweeted about the night, writing: “So proud of @goldiehawn for her work with children. And Kate so generous in coming to London to support the Foundation and her mom! Luv U!”
No sign of Goldie’s man Kurt Russell but the group surely looked like one happy family!
