#16: Demi Lovato and Madison De La Garza

Demi Lovato has conquered the hearts of fans with her inspiring songs, the journey she’s been through while struggling with demons throughout the way and the positive message she sends her fans. While it seems as if the singer has put her heart on her sleeve and revealed her private struggles with her fans, we just now realize we know nothing about her family.

For instance, did you know Demi’s little sister is a child actress? You might have recognized Madison De La Garza, Lovato’s half-sister, from her role as the daughter of Gabrielle Solis (portrayed by Eva Longoria) on the hit show Desperate Housewives.
