Lisa Marie Presley has confirmed she is pregnant - but is furious at how the news has come out.

The singer, 40, has launched a stinging attack on certain publications for forcing her into the announcement after publishing “degrading stories" and "manipulated pictures" about her weight gain.

She writes on her Myspace page, “Pardon my seething contemptuous tone but ladies, you KNOW if you were pregnant and you felt you were expanding uncontrollably by the moment as a result and the worldwide media started badgering and harassing you for it, plastering you everywhere in an unflattering light, you would be mortified as well.

“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.”

However, Lisa Marie obviously didn’t pass on her message of fury to her publicist who issued a statement on behalf of her and her husband of two years, music producer Michael Lockwood, saying, “They are incredibly overjoyed.”

Whilst it is the couple’s first child, Presley has two children Danielle, 18, and Benjamin, 15, from her first marriage.

She was also married to Michael Jackson for eighteen months in the mid-nineties, although - perhaps unsurprisingly - that coupling did not produce any kids.

Lisa Marie’s third marriage to Nicolas Cage only last three months, so he evidently didn’t have time to get her pregnant.
