Tracie Thoms is an actress best known for her roles in the Quentin Tarantino film Death Proof and the movie adaptation of the Broadway musical Rent.
Catfish is an MTV reality series best known for assisting gullible young folks who've been duped into online relationships by people who are not who they claim to be (a practice that somehow persists in 2014).

Creepy stuff, but Thoms handled the situation admirably and seemed to feel more sympathy than fear for her overzealous admirer.
