Olivia Wilde has joked she is worried she could fall victim to a crazed Justin Bieber fan. It follows a Twitter spat between the pair last week, when the Tron star tweeted the singer telling him to put a shirt on.

She claims it was a tongue-in-cheek response to pictures of him parading through London topless, but his legion of admirers have jumped to his defence and launched a hate campaign against the actress. She told CNN: "I'm going to get attacked with acid. Someone's going to throw acid in my face. If that happens there are 35 million Beliebers that did it. It's like that ballet attack, the guy who got hit. It's going to be like that but [with] Beliebers..." The 29-year old claims she has been bombarded with abuse and angry messages ever since her initial message to Justin on March 1.

"You know, it's something I'd say to my little brother, and I probably have said it. You know, just, "Put your shirt on. It's cold out there." I meant it with all the love in the world," she explained to CNN. But Justin's fans thought otherwise and she has found herself inundated with hateful messages.

Cheer up, Simon!

He's known for using his fortune and fame to help charities throughout the world.

But despite doing a good deed by attending the Red Nose Day performance of The Book Of Mormon on Wednesday night, Simon Cowell failed to see the funny side as he sported a hilarious red nose at the event. The X Factor mogul remained stony-faced as he was snapped with the comedic accessory, while Sinitta, his date for evening, posed happily in hers.

The 53-year-old star looked dapper in a grey suit and white shirt, unbuttoned to his lower chest, for the occasion. Meanwhile, Sinitta, who previously dated Cowell and has remained close friends with the mogul, looked chic in a blue striped bodycon dress.

What's happened to Khloe Kardashian?

Khloe Kardashian has been a very busy woman. While the world has been focused on her sister Kim's surprise pregnancy, it appears Khloe has undergone a quiet transformation.

Once labelled "fat" by her own mother, the newly slender reality star was looking fit and trim as she hit the shops on Wednesday. The 28-year-old showed off her toned legs in a flared leather miniskirt while carrying her new boxer puppy as she made her way into high-end baby boutique Bel Bambini in West Hollywood.

The reality star looked slim in the all-black ensemble, which consisted of the skirt, a simple V-neck T-shirt and trendy high-top trainers. Khloe was on her way to meet her sisters Kim and Kourtney at the upscale baby clothing store, no doubt to buy a few outfits for the impending arrival. She shielded her eyes with retro over-sized sunglasses, and wore her highlighted long brown hair in natural curls over her shoulders.
