It may be October, but fall isn't stopping Miley Cyrus from slipping into a sexy swimsuit.


The 20-year-old pop star posted a photo of herself lounging by the pool in a red one-piece yesterday (Oct. 19), writing:



According to Weather.com, Los Angeles enjoyed high 80's on Saturday, so obviously bathing suits were a must over Halloween costumes ...


Cyrus, who is reportedly dating photographer Theo Wenner after splitting from fiance Liam Hemsworth, has been lying low these days following her action-packed promotional tour for her new album "BANGERZ."




Rest up, Miley!
