Britney Spears, literary critic? In an online auction that began Thursday, book reports written by the 21-year-old singer while she was in junior high were among the many items put up for sale to benefit her 3-year-old charity, the Britney Spears Foundation.
Spears donated 170 items for the auction, including more than 60 stage costumes, such as the white blouse and plaid skirt she wore for her "Oops... I Did It Again" tour in 2000, and the green harem ensemble she wore for MTV's 2001 Video Music Awards, CNN reports.
In addition to the flashier stage costumes, Spears anted up numerous personal -- and less expensive -- tokens. On the block: a handmade greeting card for her grandmother, "Britney"-embroidered Mickey Mouse ears and a book report of Kurt Vonnegut's "No Talent Kid."
While opening bids for the costumes were expected to begin in the $1,000-$2,000 range, some of the smaller items, including signed photographs, began with bids as low as $150.
"It was hard to part with some of the things, but it is for a good cause," Spears said. Her foundation benefits kids interested in the performing arts.
However, some of Spears's history proved a little too personal for her to part with. Prior to the auction she decided not to offer the costume she wore on her 1992 "Star Search" debut.
The former teen queen is currently at work on her fourth album, which follows the release of "Britney" in 2001. The auction runs through June 5 at www.gottahaveit.com.
