The 'She Wolf' singer announced that she is pregnant with her and Piqué's first child in September, but has now confirmed the child's sex in a German television interview.
"It's gonna be a boy," Shakira told RTL. "This guy [Piqué] is the best thing that ever happened to me in my whole life. And now we are having a baby."
Shakira went on to promise that she will instil her love of charity work in her son.
"When the baby is born, I'll take him with me on charity trips," the singer vowed. "He shall learn that he is able to change the world."
Shakira is the founder of the Barefoot Foundation, which aids impoverished children across the globe.
She has also worked extensively with UNICEF, the Clinton Global Initiative and the Global Campaign for Education.
The singer will be joining the fourth season of The Voice USA alongside Usher as replacements for Christina Aguilera and Cee Lo Green.
