On April 18, 2005, William Regal and Tajiri successfully defended the World Tag Team Championships against the debuting Heart Throbs (Antonio and Romeo). They went on to participate in a Tag Team Turmoil match for the World Tag Team Championship at the 2005 Backlash pay-per-view, although they were unsuccessful.
The Heart Throbs, who portrayed heels, mainly appeared on the Raw B-show, Heat. They had short-lived feuds with Eugene and William Regal and Rosey and The Hurricane.
During the first episode of Heat in 2006, the pair turned face and began educating the crowd by bringing two "hot chicks" into the ring and getting them to read a book.
On February 10, 2006, WWE announced that The Heart Throbs had been released from their contracts.
