After losing husband Patrick Swayze to cancer after 34 years of marriage in 2009, Lisa Niemi will wed again. Niemi, 57, is engaged to jeweler Albert DePrisco, 58, her rep tells People. They've been together a year and a half after meeting through mutual friends at Niemi's birthday party, and "Albert proposed to Lisa on Christmas Eve," the rep says. They first publicized their relationship last October, the Huffington Post reports, and there have been rumors since last month that an engagement was near, with Niemi reportedly buying a Florida condo to be closer to DePrisco.
