In April 2005, Romeo debuted in World Wrestling Entertainment (WWE) alongside Antonio, billed as "The Heart Throbs". The Heart Throbs participated in a tag team turmoil match for the World Tag Team Championships at Backlash, but were unsuccessful.
The heel team mainly appeared on the Raw brand's B-show, Heat. They had short-lived feuds with the teams of Eugene and William Regal, Hurricane and Rosey, and V-Squared (Val Venis and Viscera).
During the first Heat episode of 2006, the pair turned face and began regularly bringing two "hot chicks" into the ring with them to dance. On February 10, 2006, both of The Heart Throbs were released from WWE.
