The "Diamonds" hitmaker will front the black-tie fundraiser in Santa Monica, California to help raise funds for her Clara Lionel Foundation.
As part of the benefit, she will also auction off a number
of personal items, including a 400 pound abstract Christmas tree which the singer put up in her home for her holiday celebrations last year (14).
Created by artist Jorge Morfin, the tree consists of five separate units covered in black ice crystal mesh fabric with over 20,000 faux black ice crystals.
