Ariana Grande Supports AIDS Awareness

Ariana Grande and big brother Frankie show off their red AIDS Awareness ribbons as they arrive at the Hollywood & Highland Center and One Heartland‘s Holiday of Hope tree lighting celebration on Saturday evening (November 28).

One Heartland is a national non-profit organization committed to greatly improving the lives of children, youth and their families impacted by HIV/AIDS and other significant life challenges worldwide.

Ariana, 16, tweeted, “One heart land is such an incredible cause! I’m so thankful to be here performing tonight! They have all of my support. So much fun singing at the tree lighting for one heart land! I just sang, it was so much fun and I’m making new friends. I’m about to go sing with them! Not planned… Haha!”
