The actress, 32, who has been wearing ring finger bling since October, is headed to the altar with James Heerdegen.
Heerdegen is a camera technician and met Ricci when the two were working on ABC's former TV series Pan-Am. Their relationship was first public last February.
Ricci most recently stepped out (and showed off her ring!) Friday to join luxury beauty brand, Make Up For Ever, in Los Angeles to introduce a limited edition bag she helped to design.
