People confirms this exciting news on its website today. The couple already have a 4-year-old daughter, Tallulah Fyfe.
Dempsey, 40, met his future wife, a stylist, in 1994 when she he came into her salon for a haircut. They wed in 1999 at the actor's family's farmhouse in Maine.
Fink now has her own high-end cosmetics line. Dempsey was a teenage star who made a comeback as Reese Witherspoon's fiancé in the 2002 movie Sweet Home Alabama and has reached new heights as the heartthrob we all know as "Dr. McDreamy" on the hit ABC drama.
"I really love it now," Dempsey said of his career. "But I also have a life outside it with Jill and Tallulah. I am really thankful that it is all going well."
