London then began a tag team with Billy Kidman on January 29, 2004. On the July 8 episode of "SmackDown!", the duo won the WWE Tag Team Championship from the Dudley Boyz. They defended the title against the Dudleys and the Basham Brothers on several occasions before losing the championship to René Duprée and Kenzo Suzuki on September 9, due to Kidman leaving London to fight by himself. Kidman's heel turn led to a feud between the two, which culminated at No Mercy where Kidman defeated London with a shooting star press. After the match, London was bleeding from the mouth and being stretchered when Kidman pulled him back into the ring with the stretcher and delivered another shooting star press to London's injured ribs. This storyline was put in place after London had broken his nose wrestling Booker T and needed time off to recuperate. London returned on November 27, wrestling on "Velocity" until the end of the year.
