When asked who was the biggest diva he's worked with, Judd said: "The most respected one would have to be Diana Ross. It was a pleasure to work with her and we all called her Miss Ross.
"But, of course, Jennifer is a diva! She is an amazing performer and a confident professional. She is always striving to be better. You have to respect that," femalefirst.co.uk quoted Judd as saying.
Despite their short-lived union, Judd insists he and the former "American Idol" judge enjoy an amicable relationship.
"I was doing a tribute for Michael Jackson at MTV and I saw her in the audience. We kind of waved at each other, and that was about it. The things that happened between us... It didn't work out, but it was amicable. We left on good terms," he said.
Lopez was married to Judd for nine months in 2001.
