Andrew Rannells Sang ‘Book of Mormon' Music at Maude Apatow's Sweet 16

Andrew Rannells might take the cake for the most random singing gig in Hollywood.

"I sang songs from The Book of Mormon at Maude Apatow's Sweet 16," Rannells, 47, revealed exclusively in his 25 Things You Don't Know About Me feature in the latest issue of Us Weekly, on newsstands now. " It was fun, but that was real random."

The Broadway vet starred on HBO's Girls from 2012 to 2017, which Maude's father, comedy legend Judd Apatow, produced.

Keep scrolling for more outrageous stories from Rannells, who appears on season 2 of Hulu's Deli Boys, out Thursday, May 28:

1. My go-to dish to cook is a turkey meatball. The kids really dig them. It was the first thing I figured out how to make that they actually liked. [Rannells' partner, Tuc Watkins, is dad to 13-year-old twins Catchen and Curtis.]

2. My most vivid childhood memory is doing elaborate lip-synch routines to the soundtrack of West Side Story with my sister Natalie.
