Shia LeBeouf goes on Twitter rant against Alec Baldwin

Shia LaBeouf just won't keep his mouth shut.

The actor - who last month quit the upcoming Broadway production of "Orphans" because of so-called "creative differences" with co-star Alec Baldwin - launched another series of Baldwin-bashing tweets Wednesday.

In his latest Twitter rant, LaBeouf posted a series of private emails from before he left the show, which reportedly come from "Orphans" director Daniel Sullivan and indicate that the often-hotheaded Baldwin was not as prepared to begin rehearsals as LaBeouf was.

"Don't be surprised if Alec doesn't look up from his script much for the first few days," one alleged email read. "I suspect he's not nearly as prepared as you are."

Ben Foster, 32, has replaced 26-year-old LaBeouf in the show, which begins previews March 26 and has its opening night slated for April 18 at the Gerald Schoenfeld Theatre.
