Kim Kardashian got attacked by angry fans of Justin Bieber when the teen sensation joked that the sexy socialite was his girlfriend.

Kardashian and Bieber frolicked in the ocean on Saturday, joking around as the two enjoyed the breathtaking scenery of their island break.

The 29-year-old Kardashian may seem a little too old for 16-year-old Bieber. But fans of the Canadian singer need not give a fuss because the two are just working together.

Both of them are staying at The Cove Resort at the Atlantis on Paradise Island in the Bahamas. They got surrounded by the crowd while having a photoshoot and doing some filming at the exclusive resort.

They walked into the sea wearing their evening dress and laughingly splashed one another as they played it for the cameras.

Kardashian has made her admiration for the singer clear.

The model met the Baby singer at the 2010 White House Correspondents' Dinner in Washington, D.C. and following that, Kardashian tweeted: "I officially have Bieber Fever!!!"

Bieber returned the compliment by posting a picture on his Twitter page with a message that said: "Look its my girlfriend Kim Kardashian."

Bieber recently claimed he is still single and may possibly date his female fans.

Kardashian, on the other hand, is back in the scene after she and her boyfriend Reggie Bush split up.

However, their joking declarations of love have brought Kardashian some problems.

"I was getting the craziest messages from all of the Bliebers. And so I was Twittering him, like 'hey Bliebs, this is crazy, getting death threats from your fans'," she said.

"I think they were 10-year-olds that got carried away, so he asked all his Bliebers to stop attacking me."
