Bailando 2021

The season was also named as "La Academia" (The academy), because participants must learn and show multiple artistic disciplines —singing, skating, acrobatics, imitation, acting— in addition to performing a dance presentation.

[4][5] A new format change was introduced for the rest of the season: In the duel, the couples will have to make a different presentation (it does not necessarily have to be dance, it can be another discipline).

Also on some occasions (in the event of a tie), María Laura "Lolo" Rossi and Eugenia López Frugoni, the choreographers chiefs, define the eliminated couple.

This season 5 couples made up of celebrities participate, they are: Ezequiel Cwirkaluk & Bárbara Silenzi; Florencia Vigna & Facundo Mazzei; Luciana Salazar & Jorge Moliniers; Pablo Prada & Lourdes Sánchez and Ulises Bueno & Rocío Pardo.

[9] Nazarena Veléz was confirmed to join the show as a new addition in round 10; but for personal reasons she retired (before her debut).

[11] In addition, a live casting was held to find the dance partner among the dancers on the La Academia's staff: Estefanía Pais, Julia «Juja» Pérez and Loana «Loli» Ruiz were the pre-selected for the position; being latter selected by the judges as a professional from Barajas.

[12] The panel of judges will be made up of four personalities associated with the world of dance, theatre, acting, singing, modelling and television.

Individual judges' scores in the charts below (given in parentheses) are listed in this order from left to right: Ángel de Brito, Carolina Ardohain, Guillermina Valdés, Jimena Barón, Hernán Piquín.

[43] de Brito returned on June 27, for the duel and the elimination of the first round (Valdés was also a participant in this process; so there were 5 judges instead of 4).

As the voices of the contestants imitating the singers were previously recorded, the judges must evaluate the lip sync (among other things).

From July 22 to August 2, Valdés returned to the judging panel but this time to replace Carolina Ardohain, who went on leave as she became a mother.

For the first time in the history of the show, a choreographer (María Laura Cattalini) from another team (of Angela Leiva & Jonathan Lazarte), who are still in competition, will replace a celebrity (Viviana Saccone).

The couples danced trio salsa involving another celebrity or a close acquaintance (friend or family member).

[58] Bal returned on September 15, this time, to replace Ángel de Brito (who was not present for personal reasons).

On September 17, in addition to Piquín's absence, Guillermina Valdés also did not attend the program due to another work commitment.

Celeste Muriega and Maximiliano Diorio, the couple facing off against Vigna and Mazzei, were automatically saved by the production.
