Rachael Ray is hitting back at tabloid rumors that her marriage is on the rocks.
During a taping of her talk show Monday, the normally bubbly cook said that constant reports about the state of her marriage to John Cusimano are starting to upset her, an observer tells PEOPLE.
"Everybody gossips ... but this stuff is hurting people's feelings who are in our families and friends of ours," Ray told the audience on the show, set to air Friday. "They worry about us."
Continued Ray, 39, "There's always someone that's going to be telling stories behind your back, but this is too much."
She also told the audience, "The tabloids won't stop printing this junk
until people stop buying it."
A spokesperson for Ray confirms to PEOPLE that she spoke about the tabloid rumors, and adds, "Rachael and John have never been happier."
According to another source, during a recent appearance in New York to promote her newly released cookbook Just in Time, Ray was asked multiple times by fans if her marriage was in trouble.
"John actually showed up at the book signing and they looked very much in love," says the source. "I bet she finally decided she needed to let her fans know she was alright and that the lies being written about her were just that, lies."
