In this video below, Jennifer talks about “World of Dance” and she mentions how she wanted everyone who would be involved to the show to be “authentically linked to dance”. That why she chose Ne-Yo, Derek and Jenna to be part of the show, apart from their individual work and what they offered to the dance community.
She talks about it at about 1:48 and more specifically about Derek at about 3:20. But a very interesting interview as a whole. Thanks Marcy for sending this!
