Giuliana Rancic Nude

Giuliana Rancic delivers the news in her birthday suit after accepting dare from Joan Rivers on her 80th

As a host of Fashion Police, Giuliana Rancic knows a thing or two about style and her TV turns always see her looking chic.

At least, they almost always do.

On Thursday the star was not delivering the news on E! in a stylish outfit but rather in the nude.

Stripping off: Giuliana Rancic delivered the news naked on E! on Thursday with a black box covering her modesty

Giuliana, 38, stood naked in front of a screen while a black ‘censored’ box protected her modesty.

She was joined by her co-star Jason Kennedy for the broadcast, who stood beside her dressed in a dapper suit.

It turns out that Giuliana stripped off because she was dared to by her Fashion Police co-host Joan Rivers.

And seeing as it was Joan’s 80th birthday, the TV star agreed to go naked.

No doubt Joan, Jason and the rest of the crew were pleased she said ‘yes’, as her fans were certainly tickled by the move.

Giuliana without clothes was just the beginning of Joan’s suitably outrageous celebrations.

The star herself rang in the milestone birthday by slipping on a dark wig, striped dress and prosthetic baby bump and pretending to be heavily pregnant Kim Kardashian.

The funny lady, who turned 80 on June 8, was also joined on the set this week by pregnant Black-Eyed Peas singer Fergie.

The 38-year-old, who proudly displayed a growing baby bump of her own, presented Joan with a frosted cake.

The birthday girl didn't waste any time digging into the sweet treat as her face became smeared with frosting.

'Cldnt resist getting @Joan_Rivers an 80th birthday present she deserved. See it go down tonight on @e_FashionPolice,' Fergie tweeted earlier this week.

Joan followed up on Thursday by writing: 'Even though the party ended in a food fight, @Fergie’s cake was DELICIOUS! All-new @e_FashionPolice tonight at 10:30!'

The veteran star also marked the occasion by mentioning her friend and inspiration - Betty White, who's 91 and still feisty as ever.

'If that's 90, where do I sign?' Joan quipped. 'I did her show, Hot in Cleveland. She knew all her lines, was running all around. After that, I thought, 80 is nothing!' 

'I feel 25 [or] 35,' adds Rivers. 'I take the stairs. Everything is working. I perform, make people happy, get a check. What could be nicer?'
