Lisa Niemi's publicist has confirmed the dancer and actress married jeweler Albert DePrisco Sunday in Palm Beach, Fla. 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.
