For the third time in a week the 54-year-old actress was spotted enjoying a romantic outing with the model, and this time it was a shopping spree at Barneys New York in Beverly Hills.
The star seemed to be so enthralled with the handsome 27-year-old that she stepped out with messy, uncombed and seemingly wet hair, reported Daily Mail.
The 'Basic Instinct' actress was dressed down in a long-sleeved black jumper and skintight grey leggings, along with a fashionable pair of black ankle boots.
Stone was wearing tinted sunglasses, but she also had a set of spectacles hanging from her collar.
Six-foot-tall Mica kept his own curly locks under control in a bun, and was dressed casually in a grey button down shirt over a grey T-shirt.
The Golden Globe winner and Mica have been dating for eight months after meeting last April at a Vogue party in Brazil where the model lived.
