Reality Show That Cast Ryan Jenkins: Oops

Producers of the reality show on which accused murderer Ryan Jenkins appeared admits it didn't do a "full" background check. What's not clear ... did it do any background check at all?

51 Minds -- the company that produces "Megan Wants a Millionaire" -- admits it was not aware that Jenkins had been convicted of assaulting a girlfriend when he was cast on the show. This is always a problem when you have someone with violent propensities sharing a house with unsuspecting strangers.

A company rep tells TMZ, "Obviously, if the company had been given a full picture of his background, he would never have been allowed on the show."

51 Minds adds, "The company did have in place what it thought was a thorough vetting process that involved complete background checks by an outside company for all contestants on the shows." In the company's defense, it was just one little mistake.

51 Minds promises to do better in the future.
