The New York Times called Jackie, Janet & Lee "deliciously readable". The Observer reviewed Diana Ross – A Biography as "fawning" and while acknowledging the comprehensiveness of the book, regretted that the writer held back unfavorable information about the subject because he was a fan. It said The Secret Life of Marilyn Monroe was written by "an indefatigable gossip hound" and criticized his vocabulary. The Gay & Lesbian Review said that Michael Jackson – The Magic, the Madness, the Whole Story was a "comprehensive and even-handed biography".
