According to NY Post, a “completely out of it” Matthew McConaughey recently joined John Mellencamp for a performance of “Little Pink Houses” at the Hollywood Bowl.

“He couldn’t open his eyes, he didn’t know any of the words … He just kept hitting his bongos randomly and muttering … When he finally left the stage, Mellencamp looked relieved and told the crowd, ‘I’m glad he’s a good actor at least.’”

Johnny, next time call Jeremy Piven?
