Their Saturday was filled with polo and hobnobbing with Hollywood's hottest stars.
Onlookers marveled at the Prince's charm and of course, the Duchess' Alexander McQueen gown.
But today the royals are off to a place where it's not the size of your entourage that matters but rather the size of your heart.
Prince William and Catherine will visit downtown Los Angeles' Skid Row, an area known for its impoverished communities and large homeless population- a far cry from the luxurious Belasco Theatre where they attended a film event Saturday night.
But nestled in this disparaged neighborhood, is a beacon of hope for a group of very special kids.
It's called Inner City Arts, a nonprofit academy for youth whose families may have been plagued by homelessness and economic troubles.
The academy teaches them to dance, sing and perform and more than that, gives them hope for a better future.
"Inner City Arts helped me discover who I am and what I want to do with my life and who I am as a person as an artist," dancer Jessica Cornejo said in an interview with "Good Morning America."
William and Catherine have chosen this as one of only a few charitable organizations that they will focus on.
Beth Tishler, Director of Education at Inner City Arts, believes they were chosen because of similar focuses.
"I think our interests are aligned with their interests, really focusing on the welfare of youth and their families and homelessness," Tishler said.
"There's so much compassion in both of them," Royal-watcher Christian Kang told the Associated Press. "I know they're going to Skid Row and I think that's very good to see from someone in his [William] position."
Afterwards, Will and Kate will meet with U.S. servicemen and women who are transitioning to civilian life.
