"We're beyond thrilled. We're actually in a state of shock right now," Dempsey said Tuesday.
Dempsey was diagnosed with late-stage melanoma four years ago and doctors told her she had less than a year to live. She survived beyond that and began dating Courtney. But soon after, doctors said she needed a double mastectomy.
Courtney asked Dempsey to move in with him so he could help her recover.
Now the couple is planning a September wedding.
As for her married name, Dempsey says she'll follow tradition and take her groom's name, meaning she'll go by Courtney Courtney.
"I love it," she said. "I'm in sales. No one will ever forget my name."
