Ariana Grande may have denied those diva rumors, but E! News host Giuliana Rancic is not letting her off the hook so easily, revealing one story that (if true) would definitely put the 'Problem' singer in the diva category.

"… I think she does have a little bit of a diva thing going on," the veteran host revealed on the show. "I don't know if that's part of the image she wants out there -- like, I'm a young Mariah, I'm a diva."

"Because I remember -- I think it was at the AMAs -- she came up on the platform, and normally I stand on this side to the camera ... yo, I had to fight 13 years to get this side to the camera, this is my good side! Little Ariana comes over, and I felt 'BING!' an elbow in my side, I'm like, 'What's going on?'" Rancic recalls. "And they pushed me to the other side! So I had to be on my ugly side!"

"Not really pushed," she quickly clarified, "But it was like, 'You either get on the other side, or we don't do the interview.' It's one thing if it's Mariah … but when you're new on the block, when you're trying to earn your stripes, you're young, I feel like, you just gotta do what you gotta do, and to try to get a great reputation and try to go overboard to please people."
