This press release from CBS threatens to destroy everything we thought we knew about Ashlee Simpson, acid reflux disease, and uncomfortable moments of panic-induced jigging:

"60 MINUTES" CAMERAS CAPTURE THE ASHLEE SIMPSON INCIDENT FROM BACKSTAGE AT "SATURDAY NIGHT LIVE" LAST WEEK FOR A REPORT THIS SUNDAY ON CBS

When Ashlee Simpson ran off the "Saturday Night Live" stage last week after her lip-sinc [sic] flap, 60 MINUTES cameras were there to record her embarrassing exit and the reaction from show creator Lorne Michaels and other shocked staff members of the show. The exclusive behind-the-scenes footage of the incident will be part of a Lesley Stahl report about the making of the venerable comedy program to be broadcast on 60 MINUTES Sunday, Oct. 31 (7:00-8:00 PM, ET/PT) on the CBS Television Network. Stahl and her cameras were also present for the dress rehearsal of Simpson's performance when she also ran off stage because her voice failed her, necessitating the now notorious live lip-sinc [sic] performance that backfired.

We're so set in our ways that it's probably going to take footage of Simpson being stabbed in the throat with a fork before we believe she had a good reason for using that lip-sync track. You know, besides the "no singing talent" reason.
