Crashing the Oscars Could Land You in Jail!

(Mar. 6, 12:30PM ET) -- Alex Deighton has never been invited to the Oscars, but now he's been officially UN-invited. TMZ has obtained a letter threatening Deighton with arrest and prosecution if he dares enter where they say he shouldn't.

TMZ first introduced you to Alex Deighton a few months back. You see, Alex is a party crasher... a gate crasher... an uninvited guest. He has made his way into dozens of A-list events -- like the Academy Awards -- without an invite and under the radar. Now it seems TMZ's story caught the Academy's eye as well.
