Kim Kardashian has just made Justin Bieber's fans jealous again. The reality TV star was seen with the Canadian pop sensation at Pinkberry in Los Angeles on Sunday afternoon, July 11.

Kardashian was wearing brown sunglasses and a bright blazer with white T-shirt underneath. Enjoying some ice cream, she tweeted: "PinkBerry's new flavor watermelon is heaven! Has anyone tried it?"

Bieber, on the other hand, wore a strip T-shirt. In a photo, he was putting a spoon into his mouth while chatting with the 29-year-old star..

His fans need not worry though because Kardashian already has a beau. She is reportedly dating Dallas Cowboys wide receiver Miles Austin.

Bieber has convinced his fans that he is not involved in a relationship with anyone and wrote on his Twitter page: "IM SINGLE and READY TO MINGLE!!"
