Jennifer Aniston Slams John Mayer/Jessica Simpson 'Love Letter' Discovery 7/10/08

John Mayer's girlfriend Jennifer Aniston has blasted rumors that she discovered "a batch" of love letters from the rocker's ex Jessica Simpson, dismissing the claims as false.

The former Friends actress, who became romantically linked to Mayer earlier this year (08), was said to have found the notes in the singer's guitar case, reports the New York Post's gossip column PageSix.

A source tells the publication, "Jennifer was more hurt than angry at the discovery. The letters surprisingly were very touching and well written." But Aniston's representative insists the story is "completely fabricated".
