With 40 million albums sold, Pink is now putting her focus on new challenges outside of music, most of all her 4-year-old daughter Willow.

"Willow is all me," the 36-year-old GRAMMY winner told ET. "She's cute like her papa, and she's mean like her mama."

PICS: Pink's Daughter Gave Her an Adorable Birthday Gift

Pink and husband Carey Hart, a retired motorcycle racer, welcomed their first child on June 2, 2011 after saying "I do" in 2006. This year, Willow is old enough to get into the spirit of the holidays, and she's already looking forward to her gifts on Christmas morning.

"Willow would like to meet Santa," Pink said. "And she wants Santa to just understand what she needs, which sounds like me with her dad actually."

Like Santa, Pink is spreading love to kids all over the world, as UNICEF's new ambassador. By helping launch their Kid Power campaign, Pink is following in the footsteps of Sarah Jessica Parker and Audrey Hepburn in helping to fight malnutrition.

"UNICEF is amazing because they're working to help children all over the world," Pink said. "This especially is amazing because 1 in 4 kids in America are inactive and 1 in 4 kids globally are malnourished. They have brilliantly, I think, figured out a way to link the two and to empower kids in this country."

Purchases of UNICEF's Kid Power Band help kids go on missions to learn about new cultures and earn points. The points earned unlock funding from partners, which are used to deliver lifesaving packets of food to children in need all around the globe.
