They're preparing for the arrival of their second child together, but becoming parents again isn't keeping singer Shakira and her partner, FC Barcelona soccer player Gerard Pique, from thinking about others who are less fortunate.

Shakira and Gerard Pique Announce They're Expecting!

In a post to her official Instagram page, the Can't Remember To Forget You singer announced that once again, the couple is setting up their World Baby Shower initiative and expanding the initial concept to also provide aid to Unicef as well, by sharing two photographs.

In one photo, the 37-year-old singer and her 27-year-old partner pose and show off her growing baby bump with their arms around one another, which announces the kick-off to the initiative.

Gerard Pique Predicted Shakira Would Have His Son

"Our second son arrives soon. We invite you to join our #WorldBabyShower for @UNICEF at worldbabyshower.org," she captioned the photo.

A second photo sees the couple with big smiles on their faces, as they also pose with their first child, son Milan, who was born in 2013.

"Your generosity made the last World baby Shower with @UNICEF a huge success! Let's see if we can help even more kids in need this year," that photo's caption read.

The singer has explained the purpose of the campaign, telling The Daily Mail that the goal is to once again help provide for the well-being and lives of children living in extreme poverty.

"Now that we are soon welcoming our second child we want to help other children around the world and also contribute to a long-lasting solution for getting children living in extreme poverty the supplies they need to survive," she said. "We also want other parents to feel compelled to do the same. With the explosion of social media, celebrities aren't the only ones who have platforms that can reach mass audiences, and we want this movement to keep going long after our baby shower had ended, so we want to invite them to host their own baby showers with Unicef as well."

The singer reportedly is urging her fans to but "inspired gifts"-including midwifery kits with medical equipment for the safe delivery of 50 babies, measles and polio vaccines, blankets and baby scales-from Facebook, which will be transformed into donations for the cause.

The couple's first shower when they were expecting Milan lasted from January-February 2013 and resulted in over 80,000 children receiving vaccinations against polio, and also oversaw the delivery of four tons of therapeutic food to help children who were suffering from malnutrition.

The couple announced they were expecting a second child together in August.
