After airing a “best of” special last week, MTV’s Nikki & Sara LIVE is back tonight with guest Austin Mahone. Obviously hosts Nikki Glaser and Sara Schaefer nailed our EW Pop Culture Personality Test. Watch the video below to find out what TV moment made them cry, what shaped their senses of humor, whose sweat rag is Nikki’s most prized possession and to whom she wrote a fan letter when she was young, and which songs were their first obsessions.

Nikki & Sara LIVE airs Tuesdays at 11 p.m. ET on MTV.
