Ashlee Simpson has blasted critics who attacked her sister Jessica’s figure, femalefirst.co.uk.

The 24-year-old singer has defended her older sibling — who was photographed wearing unflattering high-waisted jeans at a recent Florida concert with a seemingly fuller figure — insisting the comments about Jessica’s weight are “embarrassing and belittling.”

She wrote on her blog: “I am completely disgusted. Since when did a woman’s weight become newsworthy? How can we expect teenage girls to love and respect themselves in an environment where we criticize a size two figure?

“A week after the inauguration of U.S. President Barack Obama and with such a feeling of hope in the air for our country, I find it completely embarrassing and belittling to all women to read about a woman’s weight or figure.”
