American Tv chef Giada De Laurentiis and her fashion designer husband Todd Thompson have split after 11 years of marriage.

The Food Network star took to her Facebook.com page on Monday (29Dec14) to share the news, revealing they have been separated for some time now.

She wrote, "After an amicable separation since July, Todd and I have decided to end our marriage. Although our decision to separate comes with a great deal of sadness, our focus on the future and overwhelming desire for our family's happiness has given us the strength to move forward on separate, yet always connected paths.

"Todd and I share a beautiful daughter together and a lifetime of great memories that we both treasure more than anything. We are so thankful for our friends and family, and really appreciate the support in this time of change."

De Laurentiis and Thompson wed in 2003 and have a six-year-old daughter called Jade.
