Martha Stewart slams Rachael Ray: Bring on the muffins!

Stay out of the kitchen!  Things are heating up between Martha Stewart and Rachael Ray.

According to Us Weekly, Martha Stewart says Rachael Ray can't hold a spatula to her in the kitchen.  And this after she recently had Rachel on her show.

(Something tells us R.R. probably has ideas for that spatula other than flipping pancakes after hearing Stewart's slams).
