Despite their not-so chummy friendship, Amy Winehouse has donated one of her dresses to charity auction organised by Sadie Frost.
According to the Mirror, the crooner offered up one of her tiny size four frocks, after coming between Frost and her on-again, off-again boyfriend Kristian Marr.
"The two women have had a rocky relationship," a source told the paper.
