John Mayer to sell Jennifer Aniston down the river

Not quite sure who the bigger loser is here: John Mayer for threatening to spill all of Jennifer Aniston’s intimate beans in a tell-all book or Jennifer Aniston for allowing this fool to dump her twice.
“John just can’t keep his mouth shut,” a pal tells Star, “and he’s telling friends that he’s thinking of going public with all their juicy secrets.”
So just what embarrassing info could John reveal? For one, Jen made a slip of the tongue calling John “Brad“… while they were in bed! He also knows all about her obsessive exercise regime, embarrassing TV viewing habits, devotion to astrology and numerology and has witnessed the actress throw fits! [Source]
The silly thing is we already know that Jen works out obsessively. She does it because she wants to stay employed, John. As for the TV viewing habits, hello, cable is a tax write off for the ex-Friends star. And so what she likes reading her horoscope every day? Who doesn’t? My question is this: was Jennifer Aniston John Mayer’s first girlfriend? Cuz he seems to think that her habits come as a shock and as far as I’m concerned she sounds like most of my BFFs.
