Demi Lovato doesn't just want her kid sister to know how proud she is of her for her birthday! She wants the world to know!

Look at how adorable they are together! Almost as cute as when they sang this duet on stage!
Wait, is Maddie taller than Demi now? The Desperate Housewives actress is hitting those growth spurts early! Demi agrees! She said:
"What the..?!! How is my baby sis growing up so fast?!! @maddielovesyou1.. Stop growing!!!!!"
Guess we know why they call her Demi now- she's only half as tall as the rest of her fam! LOLz!
