On The Hills last night, Brody Jenner told Lauren Conrad that he was 100% sure Heidi Montag and Spencer Pratt were responsible for the sex tape rumors about her.

Of course not.

Later, Heidi signed on and claimed that someone hacked into her blog and pretended to make the above admission.

So, which do you believe?
