Singer Ne-Yo told E! about his fellow "World of Dance" judge: "I did DM J.Lo at one point about a song that I was trying to write for her [...] I didn't have her phone number at the time, so I was like, 'Alright, we'll see if she'll respond here." Ne-Yo said that while he never got a response from his co-star, he knows that she's "really busy."
