Horner discovered a love for acting after appearing in school productions of A Midsummer Night's Dream and The Maids.
In addition to performing, Horner's other creative talents include playing the guitar and writing music.
Horner was a member of the band "Earth For Now" (called "Unstable Conditions" in 2011) who played their first show in Hollywood, California, starting the set with "Howl at the Moon".
Horner and bandmate Steve Matsumura announced their departure from the band on February 2, 2012.
It appears that the actor that has taken up a role in one popular television series has been linked to his co-star of the same television series.
