Martha Stewart and Gwyneth Paltrow

Lifestyle guru Stewart snarked first in this feud, lashing out at actress (and aspiring lifestyle guru) Paltrow passive-aggressively and then less passively, stating, "If she were confident in her acting, she wouldn't be trying to be Martha Stewart." Paltrow responded, sarcastically admitting that she was "so psyched" Stewart saw her as competition, and hiring Stewart's former CEO to run her lifestyle brand, Goop.
Stewart seems to have regained the upper hand in November's issue of Martha Stewart Living, however. By titling an article about pie flavors "Conscious Coupling," the domestic diva dispenses dessert tips while also throwing shade at Paltrow's awkwardly phrased separation announcement.
