LONDON: Ashlee Simpson has taken sisterly love to the extreme. The singer has been talking up Jessica's famous curves - describing them as "incredible".

She said: "My sister has an incredible body.”

"I feel sorry for anyone who would judge her, because she's one sexy lady."

Ashlee was reacting to the media coverage highlighting her sister's apparent weight gain earlier this year.

"It's disgusting that people would say those things," she told Woman's Health.

Jessica's family have a habit of discussing her assets.

Her dad Joe famously revealed her cup size in an interview.

"Jessica never tries to be sexy. She just is sexy," he said.

"If you put her in a T-shirt or you put her in a bustier, she's sexy in both.

"She's got double D's! You can't cover those suckers up!"
