Routh proposed with a ring from Los Angeles jeweler Neil Lane earlier this month and the couple plan to wed next fall, People said.
They met "not through acting. I used to work at Lucky Strike," Routh told People, referring to the popular bowling alley in Hollywood. "I was a bartender. And her brother was having his (wedding) rehearsal dinner party there.
"He met my whole family the day he met me," added Ford.
Routh told People in June that Ford was his own personal kryptonite.
"She brings me to my knees," he said.
