The singer went on a Twitter spree Wednesday morning defending the actor's latest controversial (and wacky) behavior.
"Re: Shia. Being young and very talented/successful is like dropping in to the top fo Mount Everest via helicopter," Mayer wrote.
"There are moments in life where you need to feel quantum shift, movement. And if where you already are is considered the top…"
He added, "The dumb people disintegrate, and the smart people investigate. That investigation is never comfortable. Or all that pretty."
But Mayer is one of the few in Hollywood right now to openly support the Nymphomaniac star.
And about 30 minutes later, he added, "I AM BEGINNING TO FEEL SLIGHTLY MORE FAMOUS."
The 28-year-old Lone Survivor star then told his Twitter followers, "I TAKE IT BACK, STILL NOT FAMOUS."
But the jokes didn't end there.
"I AM...CONFUSED ABOUT HOW FAMOUS OR NOT FAMOUS I MIGHT POTENTIALLY BE...ANYMORE...," Hirsch wrote, parodying his peer. "I AM...ACCIDENTALLY ON CAPS."
LaBeouf has been garnering attention with his antics lately.
The actor stormed out of a Berlin Film Festival press conference for his latest film, wore a paper bag on his head with the words "I am not famous anymore" written for the movie's premiere, and debuted a performance art installation in Los Angeles alongside Nastja Säde Rönkkö and meta-modernist Turner.
And that's just this week!
