Shakira showed off her baby bump in a new maternity portrait with soccer star boyfriend Gerard Pique – for a good cause.

The 35-year-old singer is working with UNICEF, requesting donations rather than baby gifts for her unborn son.

She posted the black and white family photo on the couple’s “world baby shower” website where people can contibute amounts ranging from $5 to $110.

The minimum amount buys a mosquito net to protect a child from malaria, while the maximum purchases a peanut-based paste that can save a malnourished child.

“To celebrate the arrival of our first child, we hope that, in his name, other less privileged children in the world can have their basic needs covered through gifts and donations,” the couple wrote.  “Thank you for sharing this unforgettable moment with us.”

Fans who donate to the cause will receive a personalized thank you from Shakira and Piqué.

“Every expectant parent around the world shares all the same hopes and dreams for their children that we do,” the singer writes. “Yet many don’t share the same opportunities. Together we know we can change that.”
