Martha Stewart is joining the world of “Law & Order: SVU”!

According to TVGuide.com, Stewart is set to guest star on the NBC drama in an upcoming episode.

But the domestic diva will not be playing herself.  Instead, she’ll take on the role of a private school headmaster.

NBC says an airdate has not yet been set, but the episode will probably hit the airwaves sometime in late April.

Stewart has previously appeared, all as herself, on “All My Children,” “The Simpsons,” and “Ugly Betty” among other programs.
