Demi Lovato and Mariah Buzolin Have A Sleepover

So Camp Rock cutie-pie Demi Lovato took to Twitter to post a pair of pics of her and her doppelganger -- aka Hotel For Dogs star Mariah Buzolin - as they enjoy a sleepover. Seriously - these two look like the same person. They're not related but... they're twins. So, is there a separated at birth thing going on here? Are their parents involved in some crazy scheme? WTF? Anyways, they both are just cute as identical buttons.

Peace and Hugs

Are they scared or... surprised... or stunned? I dunno.
