The two blondes opted for black - with Reese arriving in a short-sleeved frock and Nicole choosing an ankle-length semi-sheer number.
Nicole accentuated her statuesque figure in her choice of outfit that she paired with black sandal heels.
Her black bra was visible under the sheer long-sleeved top while the skirt fell in lace panels from the thigh and had a front slit.
The outfit was completed with a bow at the neck and the 50-year-old wore her hair with a center parting, tumbling down around her shoulders.
Nicole added black eye liner and mascara, rosy blush and dark red lipstick.
Reese's dress featured white and silver patterns and a round neck.
The actress and producer, 41, fresh from a weekend with galpals in The Hamptons, showed off her tan as she went bare-legged in black heels.
She left her hair loose around her shoulders and sported charcoal gray eye-liner, brown brow pencil and red lip color.
