Giuliana Rancic knows viewers think she’s way too thin.

“It’s really hurtful,” the E! News host, 40, told People about the ever-present commentary on her weight. “I’m sorry that some people think I’m disgustingly skinny, as they put it, but there’s nothing I can do.”

Rancic, who’s mother to 2-year-old Duke, overcame breast cancer in 2011 and as a result underwent a double mastectomy.

“Some people were saying, ‘The cancer is probably back,’” Rancic said, who co-hosts the troubled “Fashion Police.” “And they were accusing me of every eating disorder. I thought to myself, ‘God, if someone really thought I had an eating disorder, what a horrible way to approach it.’”

In fact, her slim frame has nothing to do with an eating disorder — it’s the result of medicine she takes to suppress any return of cancer.

“I started noticing that I was eating a lot, but not gaining weight at all,” she said. “I was concerned.”

Her doctor warned her that a possible side effect is weight loss. “I’m lucky that I even have the type of cancer that reacts to the medicine,” she added.

As for her eating habits, Rancic assures she’s not skipping any meals. “I eat more than any of my friends,” she insisted. “I eat a very robust, healthy balanced diet and dessert almost every night. I’m not hiding from anything.”

Rancic, who’s releasing memoir “Going Off Script” in April, says looking in the mirror can be “hard” for her. “I am really thin,” she admits. “I want to look fit and beautiful and sexy, I can’t.”

No matter what, she never wants her appearance to take away from her work on television. “But it is becoming a distraction,” she surmises. “[Whenever] I wear something sleeveless, show my arms, my back.”
