On March 14, 2010, Alpha TV ranked Bellou the 22nd top-certified female artist in the nation's phonographic era (since 1960).
The movie "The little emigree" (I prosphygopoula) featuring the popular singer Sofia Vembo was the catalyst that pushed her to pursue an artistic career.
In the meantime, she had worked as a servant at a wealthy lawyer's house, as a hawker selling pasteli (παστέλι), as a luggage carrier and in many other different jobs.
One night she was working as a waitress in a rebetiko club in the Exarheia neighborhood of downtown Athens and sang two songs after a bet with a customer.
In December 1948, after a beating by a group of right-wingers (see Activism below), she moved from the "Tzimis o Hontros" club to the "Panagaki" where she worked with Markos Vamvakaris.
Some of her greatest hits were: Bellou was also a political activist who joined the Greek Resistance against the Axis occupation of Greece during World War II.
Members of extreme right groups never forgave her political stance and her participation in the Dekemvriana and in one incident they visited the club "Tzimis o hontros" where she was singing on stage with Peristeris, Kasimatis, Keromytis, Stelios, Roukounas and Tourkakis, and demanded that she sing a famous right wing song.
After paying for bail, she returned to her home town where she was treated with hostility and was often beaten by her relatives for the embarrassment that she supposedly brought to her family.
In her personal life, she had two big weaknesses: gambling and alcohol, which eventually led her to poverty and caused her mental problems.
