The song that Victoria competed with, "Growing Up Is Getting Old", was also internally selected and was presented to the public during a special concert on 10 March 2021.

Performing during the show in position 13, "Growing Up Is Getting Old" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 22 May.

[1] The nation achieved their best result in the contest in 2017 with the song "Beautiful Mess" performed by Kristian Kostov, which placed second.

In October 2018, the Bulgarian broadcaster announced that the country would not participate in 2019 citing financial difficulties as the reason for their decision.

On 21 March 2020, BNT confirmed that Victoria would remain as Bulgaria's representative for the Eurovision Song Contest 2021.

[2] A songwriting camp was held in Burgas and Primorsko between 16 and 26 August 2020 in order to create potential songs for Victoria.

[9] Key:   Winner   Shortlisted According to Eurovision rules, all nations with the exceptions of the host country and the "Big Five" (France, Germany, Italy, Spain and the United Kingdom) are required to qualify from one of two semi-finals in order to compete for the final; the top ten countries from each semi-final progress to the final.

[15] The LED stage floor displayed water and Victoria stroked a picture of her and her father from her childhood during the song.

The performance also featured smoke and an hourglass effect, which a stream of sand was poured in onto the stage with Victoria reaching and touching it.

The judges assess each entry based on the performances during the second Dress Rehearsal of each show, which takes place the night before each live show, against a set of criteria including: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.

[22] Jury members may only take part in panel once every three years, and are obliged to confirm that they are not connected to any of the participating acts in a way that would impact their ability to vote impartially.
