On Wednesday, Star Magazine reported that rocker Mayer was going to be writing a "no-holds-barred book – including the night Jen called him 'Brad' in bed."
"John just can't keep his mouth shut," a pal allegedly told the mag. "And he's telling friends that he's thinking of going public with all the their juicy secrets."
But as the story broke, Mayer's rep quickly issued a statement slamming the report.
Mayer is currently at work on the studio album follow up to 2006's "Continuum."
