In 2010, Catarina was invited by Carlos Coelho and Andrej Babic (the same team responsible for the song "Senhora do mar") to perform "Canta Por Mim" in the Festival da Canção 2010, the portuguese national selection method for the Eurovision Song Contest. Since the day it was presented by RTP, the song became a fan-favourite in Portugal and around Europe. It was one of the most searched songs on YouTube during the "Eurovision season" and the most played one on RTP's website. On 4 March, Catarina performed in the second semi-final of the contest, finishing 1st with 4614 votes and winning a place in the big final. On the night of 6 March, Catarina performed in the number 8 spot, preceding the winning song "Há dias assim" by Filipa Azevedo. Despite being the big favourite of the Portuguese viewers, who gave her the famous "12 points" (after receiving 10,920 phone calls), Catarina finished 2nd, since she only came 5th in the district jury's voting.
