Giada De Laurentiis Redbook MagazineGiada De Laurentiis covers the February issue of Redbook, and in the interview she opens up about her marriage and shocking rumors that she cheated on her husband with John Mayer.

A supposed eyewitness told Star magazine in November that Mayer and the 'Everyday Italian' star were spotted canoodling while partying in New York City. But Mayer's rep denied the reports and told PopEater in November that "the claims are absolutely ridiculous."

Now De Laurentiis is telling her side of the story, admitting a fun weekend in New York with Todd Thompson, her husband of seven years, and that their 2-year-old daughter Jade was turned upside down by the rumors.

"The John Mayer incident was completely unexpected. I was shocked. And not so much for me, but for my husband and family. ... Todd was embarrassed that his family in Michigan would see it and think, 'What is going on over there in Hollywood?'" she told Redbook.
