Taiwanese Superstar Sings with Shatner

4/21/2010 12:00 PM PDT
Lin Yu Chun -- aka the male, Taiwanese Whitney Houston -- will make his U.S., late night debut on "Lopez Tonight" ... and because everything is better with a little William Shatner, they're doing a duet.

The rest of the sure-to-be-epic performance airs tonight at 11PM on TBS.
