Giada de Laurentiis -- My Marriage Is Cooked

The timer has gone off on the marriage between TV chef Giada de Laurentiis and her fashion designer husband Todd Thompson.

Giada -- who's been with Thompson since 2003 -- announced their split with a flowery Facebook post that makes it sound like this will be the most amicable break-up ever. In her post, Giada says they're moving forward separately, but doing what's best for their "family's happiness."

Giada and Todd have a 6-year-old daughter, Jade Marie.

No word on if either has filed divorce papers yet. They first separated back in July.
