Rachel Bloom, Crazy Ex-Girlfriend star, was the backstage host at the Sunday night event. Neil Patrick Harris of How I Met Your Mother tweeted he wasn’t quite sure who she was, adding his 7-year-old son’s comments of her character.

Bloom tweeted back that she’s not only a fan of Harris but also her husband wrote for the show he starred on from 2005 to 2014

Bloom nor Harris’ reps have commented on the Twitter exchange.
