Giuliana Rancic was stunning at the Grammy Awards on Sunday, wearing a slim fitting black jumpsuit with sexy mesh panels.The E! Fashion Police host accessorized her look with a tiny clutch and bright red lipstick.

“I am wearing pants for the first time on the red carpet,” Rancic said of her ensemble.

“It’s definitely not faux sheer–there is no such thing,” she added to Ryan Seacrest. “It’s sheer all the way up so I couldn’t wear any sort of undergarments.”

It wasn’t all fun and games on the red carpet for Giuliana Rancic, however. She was actually dissed by a Grammy winner when trying to catch her attention for a few words.

Lady Gaga was the one who made the rather rude red carpet diss.

Giuliana Rancic tried getting Lady Gaga’s attention, and the singer, who sauntered by on Tony Bennett’s arm, glanced her way but never gave her the time of day. How rude.

@EOnlineCanada @ladygaga @GiulianaRancic SO close!

Would it have hurt Lady Gaga to raise her fingers and wave in Giuliana Rancic’s direction?

Yes, the questions typically asked of celebrities by people like Giuliana Rancic on the red carpet at events like the Grammy Awards are often glib. But let’s not forget this was on national TV.

Do you think Lady Gaga was rude or did Giuliana Rancic for some reason deserve that diss?
