LOOK OUT! GWYNETH PALTROW cornered by glam mag, bares A-list fangs.

The war between Paltrow, 41, and glam mag Vanity Fair is at a fever pitch amid her vow to destroy the mag’s rep after editors plan a no-holds-barred investigation into the GLOOP-y beauty.

“Gwyneth feels her relationship with the magazine has been destroyed and she’s urging pals not just to avoid doing business with the magazine, but to skip the mag’s Oscar party as well,” a source told RadarOnline.

 “To be frank, she wants to shut their Oscar party down entirely.”

As The ENQUIRER reported previously Gwynie sent a mass e-mail her thesppals begging them not to participate in the magazine’s expose was revealed stating: “If you are asked for quotes or comments, please decline. Also, I recommend you all never do this magazine again.”

The brouhaha erupted when Vanity Fair‘s editor Graydon Carter leaked his hard-hitting approach to Paltrow after she decided to not participate with the mag for a cover story featuring the tempestuous Iron Man co-star.

“We wouldn’t be doing our job if there wasn’t a little bit of tension between Vanity Fair and its subjects,” Carter said.

“In any given week, I can expect to hear from a disgruntled subject in Hollywood, Washington, or on Wall Street.

"That’s the nature of the beast.”

Welcome to OUR world, bro.
