Known for her spontaneous interviews and thinking-on-her-toes attitude towards live TV, Giuliana Rancic now braces herself for waves of intrigue. Is Rancic’s diva attitude the real reason behind her Fashion Police co-stars’ resignation?

According to sources, Rancic’s outrageous demands might have driven Kelly Osbourne and Kathy Griffin away from the TV program. Osbourne resigned after working for the show for five years. She has recently expressed support for Griffin with a tweet saying, she “could not be more proud” of her decision.

Griffin joined E! in January as replacement for the late Joan Rivers. Her resignation came as a shock to viewers because she has been expected to add goon-natured humor to the show. “I thought that I could bring my brand of humor to Fashion Police so beautiful people in beautiful dresses could be teased when appropriate,” Griffin said via Twitter.

Rancic’s army of stylists, make-up artists and assistants made it seem that she has a constant need for attention, compliment and validation. “It seems as if Giuliana is  trying to become as famous as the people she interviews – she even has the same stylist as the Kardashian and Jenner sisters,” the source shared. “Tapings of Fashion Police were awful because Giuliana constantly needed to have her make-up re-touched,” the source added.

The 40-year-old E! presenter has just recently faced an awkward situation during the Golden Globe awards when she hailed George Clooney to down a shot of tequila, which the actor declined. Worse still, Rancic has been quoted making an unflattering remark towards Zandaya Coleman’s hair style during the post-Oscar show. PEOPLE has since cleared Rancic’s comment and released that her full statement about Coleman’s style was, “”really heavy – it overwhelms her, and it’s just too boho.” Rancic then added that “Zendaya is more high-fashion. The hair to me on her is making her a little more boho. Like I feel like she smells like patchouli oil. Or weed.”
