Jessica Simpson strikes Demi-like nude pose for Elle

A pregnant Jessica Simpson has taken a page from Demi Moore's celebrity playbook in a nude cover photo for the April issue of Elle magazine, and the singer and actress has confirmed the baby will be a girl.

A photo inside shows Simpson standing as her fiance and the father of her unborn child, pro football player Eric Johnson, kisses her belly.

Simpson, 31, revealed in October that she was pregnant with her first child, after dating Johnson since May 2010.

As it happens, Lachey revealed this week that his current wife, TV personality Vanessa Lachey (formerly Minnillo), is pregnant with the couple's first child.

Simpson's cover photo on Elle is similar to an attention-grabbing nude pose actress Demi Moore, who was pregnant at the time, struck on the cover of Vanity Fair in 1991. The April issue of Elle featuring Simpson officially hits newsstands on March 20. Inside the magazine, she reveals that she is pregnant with a girl, confirming previous speculation.
