John Mayer and Jennifer AnistonThe third time is certainly not a charm for John Mayer and Jennifer Aniston.

Speculation that the couple has reunited was quashed by the musician himself on his Tumblr account, where he wrote a scathing criticism of the Huffington Post for claiming the pair were back together.

"Ahh, Huffington Post, the internet Death Star. The world's first spectator banking website. Come watch a site's intelligence move in and out like bellows of accordion depending on whether or not there's ad dollars to be sucked out of any willing orifice," he began.

"Huffington Post, this is reporting? How do you pay your writers now, in Silly Bandz? Do you meet your sources in a malt shoppe? This is equal parts fabricated, cobbled together and misleading," Mayer continued.
