One of my celebrity Twitter faves, William Shatner will be appearing on George Lopez's show this evening (TBS, 11 p.m. ET/PT), but he won't be alone — he'll be backing up the "Taiwanese Susan Boyle," Lin Yu Chun, in a rousing rendition of "Total Eclipse of the Heart." You may know Chun from his performance of Whitney Houston's "I Will Always Love You" on a Taiwanese talent show, which has been seen by over 12 million YouTube viewers so far. You've seen it. Trust me. Can't wait to see it all unfold? You don't have to — I've got your sneak peek after the break.
