Shakira says nothing in life compares to true love – certainly not a wedding ceremony.
"We'll get married eventually, or we won't, but we're together and that's what matters," the Colombian pop star tells peopleenespanol.com
about her longtime boyfriend, Antonio de la Rúa. "We love each other and we want to stay like that. Why fix something that's not broken?"
Shakira, 30, was in Las Vegas on Tuesday night to perform at the premiere of Love in the Time of Cholera
, for which she wrote three songs. The film, based on the novel by fellow Colombian Gabriel García Márquez, about a lifelong love affair, struck a chord with the singer.
Of love, she says, "It's my primary nourishment. I think that nothing else in life, not even your career or music – well, what I'm saying is a bold statement – I think that nothing can substitute love as the propelling force of everyone's lives. It's number one on my list of priorities, of course."
Shakira's concert on Tuesday served as a benefit for her Fundación Pies Descalzos (Bare Feet Foundation), which promotes educational development in Colombia.
