The preliminary competition was held Dec. 13 at the Planet Hollywood Resort and Casino in Las Vegas, NV.

The beautiful women from around the world were judged in segments that included bathing suits, evening gowns, and an interview.

Viewers who missed the only preliminary round can still watch the broadcast on the competition's website.

It was a tough choice for the judges who had to nail down the top beauties for the final competition. The 89 contestants were narrowed down Thursday night to 16 finalists who will compete for the top title, but viewers will have to wait till Dec. 19 to see which beauties will go on to the last round.

The preliminary competition gave fans a preview of what is to be expected at this year's Miss Universe competition, but it wasn't the only time viewers got to see the contestants.

On Dec. 14 the beauty queens participated in a costume show that heated things up.

The pageant has also created a Twitter account for fans to have their questions asked during the live broadcast on Dec. 19.

Fans will get the chance to vote for their favorite beauty before the competition by visiting Miss Universe's website, but voting ends on Dec. 18.

The 2012 Miss Universe Pageant will be broadcast live on Dec. 19 at 8 p.m. on NBC.
