Dempsey and Fink married on July 31, 1999, and have three kids together -- 15-year-old Tallula and 10-year-old twins Darby and Sullivan. The relationship hit a bump in the road in January 2015, when Fink filed for divorce. However, after looking affectionate on multiple occasions following their split, the two officially called off their divorce in November.

"You have to work at everything. And you cannot do everything," Dempsey, 51, told ES magazine last May about their marriage. "Something has to be sacrificed."

ET spoke to the handsome actor at the Bridget Jones' Baby premiere last September, when he talked about reconciling with his wife.

"That's what my heart told me to do," he commented.
