Heidi Montag is such a good friend. Heidi’s been working tirelessly to get her friend Lauren Conrad’s sex tape back. (Insert your own rolling eyes icon here) Heidi explained the situation to David Letterman on Wednesday nights show.

“I tried to help her get it back for, like, a year. I was like, ‘You gotta get it back, you gotta do something about this.’”

When Conrad’s ex Jason Wahler threatened to release it, Montag claimed, “she was like, ‘I don’t know what to do…’ I was like, ‘Well, let’s get it back.’

Asked when the tape would come out, she told Letterman, “I don’t know. I’m wondering that myself.”

Whatever!!….this is the longest wild goose chase for a non-existent sex tape we’ve ever seen.
