Lauren Sanchez shows off her athletic physique in black mini dress and sky-high heels as she and fiancé Jeff Bezos arrive by helicopter for New York Fashion Week

The lovebirds touched down on the tarmac ahead of the Staud ready-to-wear runway show on Sunday alongside friends Lydia Kives and Elsa Collins. The mom-of-two, 53, flashed her ample cleavage in a black thigh-high split mini dress embellished with a glittering design. She added height to her frame with a pair of silver platform high heels and was helped out of the helicopter by her doting husband-to-be, Amazon founder Jeff Bezos.
