“Today’s mood,” the Age of Adeline actress penned alongside a snap of Spears wearing the sparkling ensemble. “The ultimate queen who made us all want to sparkle and write and share our stories.”
“Britney, us millennials all have a story of a moment, or of years that you made us want to shine and inspire awe, with strength, and joy and immensely hard work,” Lively continued. “Thank you for your example and your contribution to women telling their stories. So excited about your biopic and all you have to come.”
