Demi Lovato & Madison De La Garza: Princess Pair

Demi Lovato plants a kiss on the cheek of her lil sis, Desperate Housewives star Madison De La Garza, at the premiere of Demi‘s new movie, Princess Protection Program, in Toronto, Canada on Thursday evening (June 18).

The 16-year-old starlet wore a strapless two-toned Alexander Wang dress — the same that singer Rihanna sported last month in NYC.

Princess Protection Program premieres NEXT Friday, June 26 @ 8PM ET/PT on Disney Channel.
