Here's Keira singing her favorite diddy of the summer, Flo-rida's 'Low' from the movie Step-Up 2. It was actually Liam's favorite, and now she sings it all day long (see actual video below).

Her other new favorite - Hannah Montana. I figured it wouldn't take long before she jumped on board the insane train that is Hannah. This is the theme song, but again, she has no clue what the words are. Doesn't really matter - sister is singing her heart out anyway...
