There's something different about the way Giuliana Rancic looked while co-hosting E! News, but we can't quite put our finger on it. Oh, that's right  she was completely naked.

Giuliana Rancic proved that she is not one to turn down a dare, as she took off all of her clothes to host the end of E! News on June 13, according to E! Online.

And why did the 38-year-old TV personality decide to bare it all?

Apparently, it was because Joan Rivers dared her to, and since it was Joan's 80th birthday this week, Giuliana was willing to oblige. Some people give their friends Starbucks gift cards for their birthday; other people get naked on national TV for them.

As you can see, the network had to cover her up with censorship bars to make sure that the audience didn't see more than it was supposed to. However, we're guessing that the show's crew got quite an eyeful.

Giuliana, who is married to Bill Rancic, underwent a double mastectomy in December 2011. The couple welcomed their son, Edward, last summer.

So if you had any doubt as to whether Giuliana had an amazing bod, we're guessing those doubts have been officially put to rest. 

And does this mean that you can tell people to get naked when you turn 80? We suddenly have a new incentive to become an octogenarian.
