John Mayer, Oscar Grouch?

(Photo: Splash Photo Agency) Mere hours away from his Oscar foray, John Mayer took to his tweet to blow off some red carpet steam, venting about the state of fashion.

"The problem I have with high style is that it's less about celebrating itself than it is about dismissing everything else."

Earlier in the week, Mayer seemed to be in brighter spirits about his high-profile date-night with Jennifer Aniston. RadarOnline.com brought you his excited pre-red carpet workout and calorie counting but it seems Mayer's nerves have made him focus on what in Hollywood unnerves him. Hopefully he'll take a cue from his yoga-loving girlfriend and chills out!
