WWW- KEITH Olbermann is thisclose to his day of reckoning for a one-night stand. The 30-something Cuban lass who says the MSNBC loudmouth courted her, bedded her, then told her to get lost, says she’s about to release the 100 or so more e- mails she claims he sent her before their night of un satisfying sex in a Manhattan hotel.

The woman, who calls herself KarmaBites and launched a blog to warn others about his boorish bedroom habits, says of the outspoken Olbermann’s refusal to say a single word about her story: “Do you actually believe KO wouldn’t deny my story publicly if it weren’t true?” And she believes Olbermann is getting heat from his new girlfriend, Katy Tur. “Methinks he’s feeling the pressure of the new squeeze to deny this publicly, but sadly for him he can’t,” KarmaBites says. “I guess my only alternative is to publish the e-mails . . . I’m tempted to re lease the e-mails just to see what excuses they come up with.” She also says the more criticism she gets from Olbermann’s fans, “the closer I get to going full-throttle and publishing all of the dirt. You’re KO’s worst enemy. I hope you can live with it.”
