Is miley and Mandy cusins

Answer 1

No, they are not they are just best friends like demi and selena:

The Miley and Mandy show began when Mandy who is a professional dancer began to teach me (Miley) a routine to Janet Jackson's, Feedback. Now Mandy has gone through a lot of dancing and performing training and well me... not so much! While Mandy taught me the dance steps we recorded ourselves so we could watch it back and remember the moves. As expected I was not so good and I began to fool around and goof off. Mandy joined me shortly after and as we were joking and having fun the camera never stopped rolling. Once we watched back the video we had made we realized that when we were just being ourselves it was much more entertaining than the dance we had put together! So, we decided to make a YouTube account and load the video and see what the reaction. Not expecting the success that it has brought, the next morning we had thousands of views and over one million messages requesting more of The Miley and Mandy Show! We began to load more and more videos and now the show has become something more than ever expected. Mandy and I have been best friends for 2 years and we are closer than ever and the show is a HUGE part of that! We get to spend lots of time together and share a lot of laughs.est friends like demi and selena.
