Two weddings and two wedding TV specials: On Saturday, Roslyn-reared J.P. Rosenbaum wed Season Eight "Bachelorette" star Ashley Hebert in Pasadena, Calif., and "Extra" host Mario Lopez and his fiancee, actress-dancer Courtney Mazza, were married in Punta Minta, Mexico.

Rosenbaum, 35, is a construction manager with the Manhattan-based The J Companies. Hebert, 28, originally from Madawaska, Maine, is a recent dental-school graduate. This marriage is the first for both.

The ceremony and its preliminaries were shot for the ABC special "The Bachelorette: Ashley And J.P.'s Wedding," airing Dec. 16 from 9 to 11 p.m.

This is Mazza's first wedding and Lopez's second trip down the aisle. Lopez's first marriage, in 2004 to actress Ali Landry, was annulled.

The two-hour special "Mario & Courtney's Wedding Fiesta" airs Saturday at 8 p.m. on TLC.
