She visited Haiti in 2015 with UNICEF to experience their efforts to aid the Caribbean nation after a devastating earthquake in 2010, and through her work with children and childcare organizations, became involved officially as an ambassador.

In fact, the mom-of-two is also driving efforts in support of UNICEF on her ongoing tour, the Summer Carnival Tour, by providing QR codes at all tour merchandise booths linking to UNICEF Market Inspired Gifts, encouraging attendees to donate and support.

She told People in 2015 about becoming an ambassador that it was motherhood that inspired her to make the move, with Willow being just four years old at the time. “The fire was lit, obviously, because I’m a mama.”

Pink served as the spokesperson for their organization Kid Power, encouraging children to embrace active lifestyles and nutrition. “Statistically, one in four kids in the U.S. are inactive,” the famously athletic and limber performer added.

“And I’m all about fitness and health and positivity. One in four kids, globally, are malnourished. So UNICEF has found a way, with Kid Power, to combat both problems at the same time.”

Of her time in Haiti, she added: “Kids are so resilient. I sat with this little 4- or 5-year-old. And she just held her hands on my face and sang to me. She’s living in a one-room shack with her entire family and hardly any food, and she’s taking the time to sit with me and sing with me…The kids give me the most hope.”
