In 2002, the singer was interviewed by Nobel Literature Prize-winning Colombian novelist and journalist Gabriel García Márquez, who was "astonished by her fantastical work-rate" and said that "Shakira's music has a personal stamp that doesn't look like anyone else's and no one can sing or dance like her, at whatever age, with such an innocent sensuality, one that seems to be of her own invention." In the United States and the United Kingdom, Shakira drew comparisons to American pop singer Britney Spears as they looked similar in appearance and sported "bleached blonde curls and butter-wouldn't-melt smiles for the kids down the front." However, critics argued that the Shakira's vocal style was very different from Spears', with Ted Kessler from "The Observer" calling the former an "operatic diva" and writing that "as soon as she opens her mouth, she slips into gear and motors powerfully past Britney's breathy bump'n'grind." In 2009, Julia Llewellyn Smith from "The Daily Telegraph" commented that "Shakira makes comparable Spanish-English 'crossover' acts such as Jennifer Lopez and Enrique Iglesias seem like minnows." In an interview with "Latina" magazine in 2011, Gloria Estefan was asked whether she felt another crossover artist like Shakira could emerge in her lifetime, to which she responded, "I'm always hopeful that somebody, any Latino, is going to succeed in what they do. And of course in music, undoubtedly." Shakira's crossover success also inspired other Latin artists to foray into the English language market and many compared Mexican singer Paulina Rubio's attempt to crossover with her English-language debut album "Border Girl" to that by Shakira.
