John Mayer named 'King Douche' for 'banging Katy Perry'

Shooter Jennings is no fan of John Mayer or Katy Perry, it's safe to assume after a recent string of tweets from the rocker. Blasting his rage out 140 characters or less at a time, the son of Waylon Jennings proclaimed the "Your Body is a Wonderland" singer to be "King Douche" on Wednesday.

What sparked Shooter Jennings' rage toward John Mayer? It was a bathroom visit spent reading Rolling Stone.

"I love how the 'neil young of our generation' self-naming king douche grows his hair out + buys a place in Montana just to do [Rolling Stone] article," the 33-year-old tweeted, kicking of a string of messages.

"Claims he's 'done w hollywood game' and has 'roots' and then immediately cuts hair, goes back to hollywood clubs + starts banging Katy Perry."

Shooter Jennings continued, "And don't anybody say he's a great guitar player. Gary Clark Jr & [Lukas Nelson] wipe their asses with this dude."

"That's enough, John Mayer," the husband of actress Drea de Matteo wrote, closing the subject only momentarily.

The two are parents of 1-year-old son Waylon Albert "Blackjack" Jennings and daughter Alabama, the latter of whom will celebrate her fifth birthday next month.

Softening his tone just a bit, Shooter Jennings added, "Sorry to s**t talk. Lord knows not everybody likes my a**. But seeing that RS in my friggin bathroom & reading the narcissistic drivel."

So far, no word from John Mayer in reply to Shooter Jennings' tweets.

Is Shooter Jennings so right or so wrong about John Mayer?
