Media reports have claimed that Anderson, who married Rick Salomon in Las Vegas last week, is two months pregnant.
However, she told gossip blogger Robin Leach: "Please tell everybody -- categorically I am not pregnant. It's just not true. ... I would tell you if it was."
Leach reported that Anderson was "celebrating her marriage last weekend with bottles of expensive Cristal champagne" Wednesday night at the party where he interviewed her.
Anderson said on her own Web site that Salomon is sensitive about the media attention surrounding them.
"So funny," she wrote. "I don't normally look at press, but Rick does sometimes. And so much nonsense. Don't believe what you read."
