Swift's fifth album already has produced a No. 1 single, "Shake It Off." She's the youngest recipient of a Grammy for Album of the Year and is the best-selling digital music artist of all time. When Swift isn't advising The Voice and topping the charts, she's busy breaking the Internet by wearing shirts inspired by Tumblr and naming her cat Olivia Benson after theLaw & Order: SVU character.

The Voice airs Mondays and Tuesdays at 8 p.m. on NBC.
