You can understand folk thinking Shia Labeouf has a Muslim background due to his full name “Shia Saide LaBeouf” BUT according to wikipedia Shia Labeouf has a Jewish background and was raised as a Jew:
LaBeouf's mother is Jewish and his father is a Cajun (once described by LaBeouf as a "Ragin' Cajun"). LaBeouf was raised in his mother's Jewish religion and had a Bar Mitzvah, though he was also baptized
Muslims should not call this Hollywood actor a “Muslim” unless Shia Lebeouf claims to be a Muslim. The internet is awash with rumours. As Muslims we should strive for accuracy and steer clear of fueling misconceptions and hoaxes concerning celebrities.
