Lisa Marie Presley has sued a British newspaper for alleging that she was piling on the pounds because of her unhealthy appetite, her lawyer said Monday.

Presley, who is pregnant, alleges in a suit filed at London's High Court on Friday that the story in Britain's Daily Mail was slanderous and degrading. The newspaper has since reported on the 40-year-old singer's pregnancy.

"Once they got a glimpse of my expanding physique a few days ago, they have been like a pack of coyotes circling their prey whilst eerily howling with delight," she said on her blog.

The daughter of the late singer Elvis Presley claims the pictures taken at a Hollywood restaurant last week forced her to go public about the baby she is having with her fourth husband, music producer Michael Lockwood.
