Kim Kardashian and Lewis Hamilton are keeping their romance going strong while continuing to support each other's career endeavours.

On Wednesday, May 6, the 45-year-old reality star and the 41-year-old F1 champion were spotted walking hand in hand after attending The Fear of 13 on Broadway in New York City. The production, backed by Kardashian, is a drama centred on wrongful conviction and death row themes closely tied to her criminal justice advocacy.

The SKIMS founder sported an all-blue ensemble, including a long-sleeve corset bodysuit with cutout sleeve details and light-wash jeans. She completed the standout look with a pair of silver heels.

Meanwhile, Hamilton donned a monochromatic beige jacket and matching trousers for the outing, paired with dark brown lace-up shoes.
