Maria Isabel (María Isabel López Rodríguez) was born on January 4, 1995 in Ayamonte, Andalucia, Spain) is a singer and the winner of the Junior Eurovision Song Contest 2004.

María Isabel demonstrated an interest in dancing and singing from a very young age. As a child, she proved to be vivacious, hyperactive and dedicated to her hobbies of dancing and singing. She also developed a love for birds, which led her to begin a collection of birds that she still maintains.

Her love for dancing and singing took her to a competition, in 2004, named "Eurojunior", which was televised nationally in her native Spain, and designed to choose Spain's representative in the relatively new contest, "Festival de Eurovision Junior" (Junior Eurovision Song Contest), begun in 2003, which is a children's version of the famous Eurovision festival that has launched the careers of many European singing stars over decades.

María Isabel won Spain's "Eurojunior" with her single "Antes Muerta que Sencilla" ("I'd rather be Dead than Plain"). Later on, she won the second "Junior Eurovision Song Contest" using the same song, beating the second place contestant by a total of 171 points, which constitutes, so far, the largest margin by which a person has won the junior version of "Eurovision".

Some weeks before winning the festival she released her first CD, named "No me Toques las Palmas que me Conozco" ("Don't Play the Palms Because I Know Myself"). This CD included "Antes Muerta que Sencilla" and launched her career in the Spanish show business world, making her a competitor of another Spaniard teen idol, Melodía Ruiz Gutiérrez.
