4 P.M. Fashion Fix: Tavi Hits Late Night

Tavi's hobnobbed with the likes of the Mulleavys, Ira Glass, Iris Apfel, and now she can add another famous acquaintance to the mix.

The precocious teen recently appeared on Late Night With Jimmy Fallon, where she naturally charmed the audience with an anecdote about meeting Bjork and explaining what exactly "bitch face" is (we're well-versed, Tavi).

She more than holds her own against some of the Hollywood heavy-hitters who've appeared in the seat before her.
