Heidi Montag was on Letterman last night, and she elaborated a little more about the whole Lauren/Jason sex tape scandal. She totally says that Lauren confided in Heidi about the fact that Jason was about to sell the sex tape and she didn't know what to do and Heidi was helping her to try to get the tape back. As cheesy as Heidi is (seriously, that hair! Miss J. would call her a "no-neck monster"), and as slimy as Spencer can be, hearing Heidi's side of the story was a little eye-opening. Clip above.
