The socialite added an olive green jacket lined with a fleece and kept her sunglasses on as she strolled.

Nicky's long blonde hair had loose waves and blew with the wind as she walked side-by-side with her husband.

She looked to have gone for minimal makeup, highlighting her natural radiance with just a bit of foundation.
