Throughout his career, entertainment reporters have attempted to link Siller to high-profile co-stars. During his early years at Televisa, particularly after his breakout role as Luciano in the teen drama Rebelde (2006) and his lead role opposite Allisson Lozz in Al diablo con los guapos, the Mexican press routinely ran blind items alleging off-screen romances. None materialized into verified relationships.
Rumors later paired him with actress Danna Paola during the filming of Telemundo's ¿Quién es quién? (2015, 2016), and with Vanessa Villela. In each instance, Siller maintained complete silence or dismissed the speculation as camaraderie between hard-working colleagues.
