The blonde beauty, 25, met Purcell, 42, on the set of the film Officer Down in 2011 and they enjoyed a 15-month romance before reportedly splitting in October (12).
They were subsequently spotted hanging out together on multiple occasions, and now McCord has confirmed they are boyfriend and girlfriend once more.
Gushing about her man, she says, "I have a lot of respect for him. He's a really wonderful man."
However, that doesn't mean McCord is hoping for a proposal in the near future, even though everyone around her seems to be getting married.
She tells UsMagazine.com, "It's like 2012 was the year for engagements. My two sisters got engaged, Shenae Grimes got engaged. But I am very happy in my long-term, committed boyfriend-girlfriend relationship. I am not getting married!"
Grimes' model boyfriend Josh Beech proposed to the actress last summer (12) after just months of dating.
