Jessica Simpson remains mum on pregnancy rumors

Jessica Simpson has remained mum on pregnancy rumors, despite appearing on the cover of OK! magazine with the headline, 'Yes, I'm Having a Baby.'

The accompanying story quotes a "close friend" as saying, "Jessica is so excited... She joked, 'Well, now I can eat anything I want and no one will care. It's just sort of a rule with pregnant women.'"

Simpson's representation had no immediate comment.

The singer's father seemed to have an opinion on the rumor-mill though. "Makes me crazy when people lie about my children!!" Joe Simpson wrote on Twitter on October 20, without elaborating.

Simpson hasn't denied nor confirmed reports that she's expecting a baby with fiancé Eric Johnson. Simpson and Johnson began dating in May 2010 and announced the following November, after he finalized his divorce from his first wife, that they are engaged. No wedding date has been announced.

This will also be the second marriage for Simpson. She and her first husband, Nick Lachey, on the MTV reality show "Newlyweds: Nick and Jessica", which documented their married life together. The two divorced in 2006. Lachey and television personality Vanessa Minnillo wed in July.

Simpson, known for her voluptuous figure, has been the target of rumors for several months. She recently responded to reports that she was getting a breast reduction, telling fans that her breasts "aren't going anywhere."

Simpson has in recent years focused on her fashion endeavors. Her collections of apparel, perfume and other products, which are marketed to young women, have raked in almost $1 billion in sales.

The singer recently launched her own line of diamond jewelry with Zales and also teamed up with celebrity aesthetician Nerida Joy to launch BeautyMint, an online portal that sells anti-aging skincare.

Simpson is already an aunt to her sister Ashlee's 2-year-old son Bronx Mowgli.

In February, Ashlee Simpson filed for divorce from Pete Wentz, a 32-year-old member of the rock band Fall Out Boy and the father of Bronx Mowgli, their only child. They married in May 2008.
