James Frey is either brave or masochistic. He’s agreed to be one of Oprah Winfrey‘s final guests on her syndicated show, even though she famously filleted him for fabricating details of his best-selling memoir, “A Million Little Pieces,” in 2006. The controversial writer — who was so burned by Winfrey’s wrath that he had to flee to France — will face his former nemesis for a full hour next month to promote his novel, “The Final Testament of the Holy Bible,” out tomorrow. A source told us, “Oprah apologized to James a couple of years ago, and he appreciated it. So he agreed to go back on her show and talk about everything that’s happened over the last five years.” Frey is set to ignite another fire storm with his new book, in which the Second Coming of Christ takes place in the Bronx projects — but the messiah turns out to be a former alcoholic who impregnates a prostitute. It’s being published in a limited edition of 10,000 copies by Gagosian Gallery and as an e-book by Frey and WME. Reps for Winfrey didn’t get back to us.
