The blonde beauty appeared on the red carpet in Italy on Saturday, July 31, at the LUISAVIAROMA and UNICEF Gala in Capri. Lee looked radiant in a strapless yellow Matičevski gown with a sultry slit to show off her legs paired with Miu Miu stilettos, an Amanda Pearl clutch and a 30-carat ruby cocktail ring, PEOPLE reported.
"I'm having the best summer of my life," Lee told the outlet at the event. "I'm here to support UNICEF and the amazing work they do for children around the world," she said, as she marks 25 years as a founding board member of UNICEF's Los Angeles chapter and as the sole International Emissary.
Lee took her 115,000 Instagram followers along with her for the night and shared a clip of her dancing on Instagram.
"Welcome to the party…. so so so much fun—love Barry White—I’m going to love ya love ya love ya —literally one of the best nights ever! THANK YOU GOD FOR THIS AMAZING SUMMER!!! Love to you all, always and forever!! Xo sl," she captioned the post.
