Martha Stewart threw some serious shade on wanna-be Gwyneth Paltrow ... scoffing at our photog's question ... Who's the better lifestyle coach?
Watch Martha blanche at the question, as if the conclusion is painfully obvious.
Her answer has merit -- Martha's run a major lifestyle company for decades. Gwyneth blogs a lot. Martha sells enough stuff to furnish a house. Gwyneth tells you where to buy things you can't afford.
And Martha's been to prison and knits a shawl.
Take that Gwyneth.
