Lopez was married to Judd for nine months in 2001 and the dancer admits the 43-year-old is still a "diva" for him, reported Contactmusic.
"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's an amazing performer and a confident professional. She's always striving to be better. You have to respect that," Judd said.
Despite their short-lived union, he insists he and the former 'American Idol' judge are still on good terms and have an amicable relationship.
