Pat O'Brien

Former Access Hollywood and The Insider anchor Pat O'Brien intends to write a tell-all detailing his struggle with alcoholism and his "unfortunate scandal," in which he left slurred sexually graphic voicemail messages on a woman's phone, he tells the New York Post.

O'Brien, who will co-write the memoir — tentatively titled I Love Your Work — with biographer Andrew Morton, will also address his 2004 divorce from his wife, Linda, which occurred a year before his voicemails leaked.

In the voicemails, O'Brien asked an unidentified woman to join him for drugs and sex. He subsequently entered rehab before returning to The Insider. He did another stint in rehab in March 2008 and six months later was fired from The Insider after writing e-mails to co-workers that insulted co-host Lara Spencer.

"I was not in total recovery at the time. I was still messed up," O'Brien, 62, told the Post's Page Six.

O'Brien, who says he's been sober for more than 600 days, is considering a multiyear radio deal.
