The pair have been spotted together at premieres and events over the past two years, but have chosen to keep their relationship private.

Caplan, who played Virginia Masters on Showtime drama “Masters of Sex”, previously dated former “Friends” star Matthew Perry. She and Riley, 36, met in London in January 2015, and became engaged last summer.
