Visitors can cast bids on Taylor's necklace and shoes, a meet-and-greet with the Jonas Brothers, autographed guitars from Melissa Etheridge and Avril Lavigne, a tambourine signed by Brian Wilson and dozens of designer items once owned by Paris and Nicky Hilton.
Hilton held her first auction to benefit the Make-A-Wish Foundation last Christmas and plans to make it an annual tradition. Her auction raised more than $27,000 last year.
