Last week, Shakira tweeted that she would have to miss scheduled performances at the Latin GRAMMYs, as well as the American Music Awards, for personal reasons.

"Due to personal matters, I won't be able to travel to Las Vegas & LA to attend the @LatinGRAMMYs or the @AMAs this year," she wrote. "I will be accompanying @carlosvives in spirit @LatinGRAMMYs, celebrating this incredible year that we’ve shared together with #LaBicicleta."
