Miley Cyrus arranges to party about her 18th birthday with her divorcing parents: The 'Hanna Montana' star, who turns 18 Nov 23, is planning a low-key family get together. 'We need time to all be together... I'm not going to go crazy; (I may) have a fun party and then maybe take a vacation with my family because that would be really cool,' contactmusic.com quoted her as saying. 'I have to be near the water and I love doing scuba and going out and being on a boat,' she added.
