Giuliana Rancic calls out Ariana Grande for diva behavior

LOS ANGELES, Sept. 18 (UPI) -- Giuliana Rancic has confirmed Ariana Grande's penchant for diva antics.

Grande has earned a reputation for difficult behavior in recent months, including an alleged incident where she walked out of a photo shoot in Sydney. Sources claimed the 21-year-old singer left because she wasn't happy with the pictures, and Rancic related a similar run-in she had with the star at the 2014 American Music Awards.

"I think she does have a little bit of a diva thing going on," the Fashion Police host revealed on E!. "I remember, I think it was at the AMAs, she came up on the platform, and normally I stand on this side [her left side] to the camera. I had to fight 13 years to get this side to the camera, it's my good side, but I fought 13 years for this, okay?"

"Little Ariana comes over, I feel like 'bing,' elbow in my side. I'm like, 'What's going on?' and they push me to the other side," she continued. "So I had to be on my ugly side. But I felt like a little bit of a, you know it was like, 'You either get on the other side or we don't do an interview,' and I just felt like it's one thing if it's Mariah [Carey], you know, I'll get on any side, I'll bend down, I'll climb a ladder, whatever it takes to get Mariah to do an interview."

"But when you're new on the block, when you're trying to earn your stripes, you're young. You just gotta do what you gotta do, try to get a great reputation, try to go overboard to please people," she reproved.

Grande denied she stormed out of the photo shoot in an interview with Mike E and Emma at 96.1. The singer claimed she left the shoot to merely change her top, and called the rumor "ridiculous" and "untrue."
