"It is with great sadness, that after 17 years, a tremendous amount work, careful consideration and heavy hearts, my wife and I have mutually decided to no longer remain married," Cat, 48, tells PEOPLE exclusively. "In love, there is a season, a reason and a lifetime."
The first female Iron Chef and Jennifer, 44, are parents to four sons, Zoran, 11, Caje, 8, Nash, 6, and Thatcher, 6, all welcomed via in vitro fertilization.
"Although this is not what we ever imagined, we will always have four incredible reasons to celebrate our years together: our sons," says Cat. "We are forever parents to our boys and are jointly committed to raising them in a peaceful, nurturing and healthy environment."

In a 2010 interview, Cat revealed their path to parenthood was an unconventional one.
"The doctor implanted Jennifer and me with each other's eggs," she said. "So she gave birth to Caje, but he's my biological child. I carried Nash, but he's Jennifer's biological child."
"As a same-sex couple, we had to go back and legally adopt them," she added. "Even though Nash was her biological son, Jennifer had to adopt him. Same with me and Caje."
