Along with carrying a baby on the Late Show with David Letterman last night, the Flaming Lips' Wayne Coyne took part in a Reddit AMA session.

He answered questions about how hot the ball gets during live performances, how to get picked out of a crowd to dance with the band and working with Ke$ha: "She's funny, she's humble. She's badass. She's everything. She's awesome."

Their latest album The Terror is out now via Bella Union.
