London made his debut in WWE in late 2003, and immediately began teaming with fellow cruiserweight Spanky, (Brian Kendrick). After Kendrick briefly left WWE, London formed a tag team with Billy Kidman, and together they won the WWE Tag Team Championship. After their split, London began competing in the cruiserweight division, and won the WWE Cruiserweight Championship. In late 2006, Kendrick returned, and the two reformed as a team. London and Kendrick were previously managed by WWE Diva, Ashley Massaro, who London has previously dated. The team split when Kendrick was drafted to the SmackDown brand in June 2008.
