Monica Lewinsky is shopping a top-secret book project, Page Six has exclusively learned. We’re told Lewinsky has been making the rounds with major publishers, who were all asked to sign nondisclosure agreements to take the meetings. It’s unclear who the front-runners are, but, says an insider familiar with the project, “I’m sure every major publisher was interested in hearing what she had to say.” The former White House intern who touched off the 1998 Bill Clinton scandal has given past interviews, but kept a very low profile since leaving for England in 2005 for the London School of Economics. Lewinsky’s rep said yesterday, “I cannot comment on anything at this point.”
