Casey Affleck, 47, rocks a casual black look at the amfAR Gala with girlfriend Caylee Cowan, 24

Casey Affleck was all smiles as she rocked a casual all-black look as she hit the red carpet with girlfriend Caylee Cowan at the amfAR Gala.

The 47-year-old actor posed Thursday evening with his 24-year-old actress girlfriend during the annual gala at the Pacific Design Center in Los Angeles.

The actor first met Cowan in January 2021 and started dating later that year and they certainly seemed like a very happy couple on the red carpet.
