Her most notable recurring guest roles on television have been as Black Diamond in the critically acclaimed TV show Snowfall (FX) and as Mabel in Black Mafia Family (Starz). In addition, Horn has starred in many productions, including Grey's Anatomy (ABC), NCIS: LA (CBS) Black-ish (ABC), The Lincoln Lawyer (Netflix), Shameless (Showtime),the award-winning feature film The Fallout (Warner Bros), and Terminator: Dark Fate, among others.

Although acting became Horn's first love, music was never far behind. She started her own record label and production company (Chocolate Superstar Productions) and released two successful projects on iTunes: her debut album, “Walk With Me” and her internationally released sophomore album, “Therapy.” When it comes to her music, Christine does for soul music what a hit play does for Broadway. She enriches it by expanding its boundaries. Her use of melody, language, dialect and drama enables her to touch those who are searching for that extra bit of enlightenment, individuality and entertainment in their music.

When she's not performing, Christine is also a coach to mentees in her Hollywood Bound Actors virtual community. Believing in the “each one teach one” mantra, she is passing the baton to new and uprising creatives by giving back to the acting community that has blessed her beyond measure.
