UPDATE: Miss Universe 2012 Top 16 Revealed!
The show will feature 89 of the most beautiful women of the world vying for the top honor currently held by 2011 winner Leila Lopes.
A preliminary competition was held on Dec. 13 where the women were judged in segments that included bathing suits, evening gowns, and an interview.
According to the Las Vegas Sun, the contestants were narrowed down to 16 finalists who will be announced later this evening. Viewers who missed the only preliminary round can watch last night's broadcast on the competition's website.
The preliminary event was followed by a national costume show where the contestants got to display a variety of interesting outfits for fans.

Andy Cohen, Executive Vice President of Development and Talent for Bravo, will return to host this year's beauty competition for the second time in a row. He will be joined by E! News anchor Giuliana Rancic.
