“RENO 911!” star Niecy Nash has pulled the plug on her 16-year marriage to Don Nash, an ordained minister and real-estate entrepreneur. “It’s unfortunate . . . however, after much prayer and counseling, we felt it was the best decision for us. Everything was amicable and we will always have a great deal of respect and support for one another,” Niecy told us. The couple have three children. Tomorrow, Niecy will accept a Gracie Allen Award from American Women in Radio & Television at the Marriott Marquis for her work on the Style Network’s “Clean House.”
