Fans of Univision's "Nuestra Belleza Latina" are only a couple of days away from finding out which beauty will win the contest's ninth season, the Spanish-language television channel recalled.

The champion is to be announced this Sunday, and the final episode will feature "super-star guests ... to celebrate the crowning," Univision added.

Still in the running for the title are Nathalia Casco, representing Honduras; Catherine Castro, representing Puerto Rico; and Clarissa Molina and Francisca Lachapel, both representing the Dominican Republic. The winner will be awarded a contract to be one of the new personality faces on many of Univision's programs and award shows; she will also receive some $200,000 in cash and prizes.

For Sunday's finale, meanwhile, the channel has spared no expenses and is promising a glamorous show.

Among the highlights will be a duet by New York singer-songwriter Prince Royce and legendary bachata singer Anthony Santos, who together are set to perform "Que Cosas Tiene el Amor."

But the list of stars does not end there.

Puerto Rican pop star Ricky Martin will participate with his hit single "Disparo al Corazón," while Mexican Regional music singer Espinoza Paz will sing his new ranchera, "Perdí la Pose." Also invited are former Timbiriche member Paulina Rubio, who is set to interpret "Mi Nuevo Vicio," and Puerto Rican reggaeton artist J Alvarez, who will perform "Temperatura."

Aleyda Ortíz, the queen of the last "Nuestra Belleza Latina" season, will sing and dance a special number before passing on her crown. Ortíz, who represented the U.S. territory, had also been the first runner up at Miss Universe Puerto Rico 2014 and represented the island at Miss Intercontinental 2013, where she won in the "Best in Swimwear" and "Best Smile" categories.

Before Ortíz's successor can be determined, the four remaining contestants will have to tackle their final challenge, Univision said. Casco, Castro, Molina and Lachapel are going to showcase their camera and stage skills in performances with a famous guest comedian, the channel detailed.

Univision's "Nuestra Belleza Latina" finale airs at 8 p.m. on Sunday, April 12.
