Arnelas was born in Valencia de Alcántara, Cáceres, Spain on 13 September 1982.

She wanted to study drama but soon started working as an airline stewardess for Iberworld,[1] where she travelled around the world.

Her début album Corazón De Fuego was released on 5 December 2005 produced by Kike Santander.

The album includes covers of 1980s hits, including Kylie Minogue's "I Should Be So Lucky", Cyndi Lauper's "Girls Just Want to Have Fun", Eurythmics's "Sweet Dreams (Are Made of This)", Modern Talking's "You're My Heart, You're My Soul" and the lead single, "Dolce Vita", a cover from the Italian singer Ryan Paris.

By the end of 2008, she submitted one of the songs from her latest album, Sin Miedo, "La noche es para mí" to the Spanish preselection for the Eurovision Song Contest 2009, being considered the early favourite to represent the country.

Being an automatic finalist representing Spain, she performed in the 25th position on Final night, finishing second to last.

Arnelas referred to the score as a punishment from Europe, for Radio Television Española's late airing of the second semi-final where Spanish televoters and jury members were to vote.

Previously to her Eurovision experience, she participated in the reality talent contest La Batalla de los Coros, the Spanish version of Clash of the Choirs.

The first single to be released from this album was "Live Your Dreams", an electronic-dance-pop song, produced by French DJ Antoine Clamaran.
