It's been battle of the Lifestyle Gurus this week as Gwyneth Paltrow and Martha Stewart come to head about their brands.
Martha dismissed Gwyneth's ventures into the lifestyle arena with her Goop site, saying she is just a "movie star".
She said: "She just needs to be quiet. She's a movie star.
"If she were confident in her acting, she wouldn't be trying to be Martha Stewart."
Martha Stewart told Gwyneth to stick to actingBut Gwyneth has her say too.
Speaking at the Most Powerful Women Summit in Laguna Niguel, California, she sarcastically said: "No one has ever said anything bad about me before, so I'm shocked and devastated. I'll try to recover."
She then admitted: "If I'm really honest, I'm so psyched that she sees us as competition. I'm so psyched. I really am.
"At this point in my life I don't take it personally."
Earlier this week, Gwyneth announced she had hired Lisa Gersh, the former CEO and president of Martha Stewart Living.
Lisa said of her appointment: "As a fan since its launch, I've admired the inimitable voice and style Gwyneth has infused into goop, and the business she's built.
"It's rare to work with such an inspired founder and a digitally native company, a brand that thinks digitally from an organic point-of-view and successfully fuses content and revenue-generating retail."
