Busted. Again.

Oops!

Shia LaBeouf was caught smoking somewhere he shouldn’t have been…again.

According to reports, Shia just couldn’t quell his need for a cig while filming a Transformers 2 scene at the “no smoking allowed” Smithsonian National Air and Space Museum in Washington, D.C.

Shia reportedly set off a smoke detector alarm when he lit up in the men’s room. Sources say he endured a stern lecture, topped by a warning he├óΓé¼Γäód be ejected from the museum if he lit up again.

Give up the dirty habit already!
