The actress and her pop sensation of a sibling share their mother, Dianna De La Garza and recently Demi shared some snaps of the pair celebrating Madison's sweet sixteen.
And because it's still such a household favourite it's easy to forget that some of the younger cast members are fully grown teenagers and we can't believe that Madison De La Garza who played Juanita Solis - daughter of Carlos and Gabriella - just turned sixteen! The former "Desperate Housewives" actress wore a white romper with removable sheer skirt for her winter-wonderland themed event, and not only does she look so different than she did when she portrayed Juanita Solis on the TV series, but she looks just like her big sis!
Madison looked darling in a sweeping sleeveless white gown with a diamond encrusted belt wrapped around her waist. She shared one image from the night with fans. "Look at how gorgeous you look!"
We're glad that Lovato and De La Garza are in a better place now, because they have a lot of happy (and twinning) moments ahead of them.
Madison and Demi did some singing and dancing too, enjoying hits like Fergie's "Fergalicious", Justin Timberlake's "Rock Your Body", and, Lovato's song with Luis Fonsi, "Not On You". The teen's mom Dianna De La Garza, father Eddie De La Garza and sister Dallas Lovato were also at the shindig.
We're so happy to see Demi attending such a special event in her little sister's life considering there was a period in the "Sorry Not Sorry" singer's life where her family almost cut ties from her. "Everyone was like, 'We are no longer going to leave, we are leaving, ' " Lovato recalled during an appearance on The Jonathan Ross Show. Let us know in the comments, below!
