Orlando Bloom had thousand of dollars worth of jewelry stolen from his home last night because he's not smart enough to keep it somewhere safe. We're not talking about a couple rings and a necklace, the stash is estimated around $500,000 worth of jewelry!

Orlando Bloom had hundreds of thousands of dollars worth of jewelry in his Hollywood Hills home. Notice the past tense, because we've learned burglars made off with the bling last night. Law enforcement tells us the thieves entered Bloom's house through a window and made off with roughly $500,000 in jewelry -- including two very expensive watches.

Police say it doesn't look like a typical burglary, but won't comment on whether it could be an inside job or not. That will teach him to not keep that amount of bling in his home.
