Alec Baldwin, who once had a feud with Page Six — we made up — is now at war with Mike Walker of the National Enquirer. The day before he co-hosted the Oscars, Baldwin — angry at Walker for reporting he’d screamed at Tina Fey on the set of “30 Rock” — told the Times of London the veteran columnist was a “whore” and a “queen.” Walker vents in this week’s Enquirer: “Here’s my headline: ‘Alec Baldwin — Raging Closet HOMOPHOBE!’ Grab your pitchforks and torches, Hollywood — the monster lurks among ye!” Baldwin, who says he never screamed at Fey, doesn’t seem to be afraid of a gay backlash. He told us yesterday, “Yes, he [Walker] is a goat-footed, wheezy, old queen, and all my male lovers agree with me.” Walker states, “Just for the record: I am not gay, as my wife will attest. Right honey? . . . HONEY?? Hey Alec: Stay tuned.”
