(Undated) -- "Transformers" star Shia LaBeouf is making transitions. In the midst of a growing plagiarism scandal, the 27-year-old actor tweeted early Friday morning that he was "retiring from all public life" in light of the recent attacks against what he called his artistic integrity. On Thursday, LaBeouf tweeted out a cease and desist letter from the legal team representing the comic artist whose work LaBeouf is accused of plagiarising for his own short film "HowardCantour.com." The actor earlier apologized for the failing to credit Daniel Clowes for his work, which he says served as the inspiration for his movie.
