Niemi, 57, and DePrisco, 58, met through mutual friends, then dated for more than a year before getting engaged last Christmas -- a little more than four years after her first husband, actor Patrick Swayze, died of pancreatic cancer.
Niemi and Swayze were married for 34 years, and co-starred in the 2003 film, One Last Dance, which Niemi also wrote and directed. Her other film acting credits include She's Having a Baby and Swayze's movie, Steel Dawn.
Swayze was best known for his roles in The Outsiders, Dirty Dancing, Ghost and Road House.
