Role gall as Alec will play a journo

Now Alec Baldwin can hate himself.

The blowhard actor, fresh off his rant in New York magazine about how much he hates the media, will play a newspaper columnist in an upcoming episode of “Law & Order: SVU.”

Baldwin, whose targets in the magazine’s story include his former MSNBC colleagues, will play Jimmy McArthur, “who questions the SVU squad’s motives” during a hate crimerape investigation, according to NBC’s description of the episode.

It’s called “Criminal Stories” and will air March 19. Series costar Mariska Hargitay, who directed the episode, noted Baldwin’s “fierce commitment.”

The 55yearold Baldwin, saw his littlewatched, shortlived MSNBC talk show axed in November after he allegedly called a photographer camped outside his apartment “a cksking fg” — although he copped only to calling him a “cksker.”

And he has a long and volatile history with the media.

The star, who lives in the Village, called a reporter for the British tabloid the Daily Mail a “toxic little queen” last June after it reported that Baldwin’s wife, Hilaria, was tweeting during the celebritypacked funeral of “The Sopranos” star James Gandolfini.

In New York magazine, Baldwin labeled former MSNBC colleague Joe Scarborough “neither eloquent nor funny,” and called host Rachel Maddow “a phony who doesn’t have the same passion for the truth offcamera that she seems to have on the air.”

Baldwin also threatened to move out of New York City — saying that “everything I hated about LA I’m beginning to crave . . . Manhattan is like Beverly Hills and the soul of New York has moved to Brooklyn, where everything new and exciting seems to be.

“I have to accept that.”
