Ashlee Simpson and Teen People magazine have put together an auction to benefit UNICEF's relief and recovery efforts for the young victims of the Dec. 26 Asian earthquake and tsunami disaster.

Simpson asked her friends to collect unique items that are being auctioned on eBay until Monday afternoon (5 p.m. EST). Proceeds will benefit the U.S. Fund for UNICEF.

"The tsunami and its aftermath have affected everyone, and I couldn't imagine sitting silent and not doing anything to help. I approached Teen People to partner with me to raise money to help everyone affected by this disaster," the 20-year-old singer said in a statement Wednesday.

The auction includes phone calls from stars such as Chad Michael Murray and Shane West; concert experiences with Simpson and New Found Glory; autographed merchandise from Jessica Simpson, Good Charlotte and Nicky Hilton; and sports memorabilia.
