"It's true," says a rep for the actress. "They're thrilled."
This will be the first marriage for both. No wedding date has been set.
Larter, 31, has made it clear she has been more than ready for a proposal from MacArthur, who recently appeared in The Game Plan.
"I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow," Larter recently said. "I look forward to that time when I'm home with babies."
And in August, Larter she was madly in love, adding that MacArthur has "brought light to my life. I feel lucky every morning when I wake up and see him."
