Rob Kardashian pled ''not guilty'' in court today (08.05.13) after being charged with attacking a female photographer in March.

The 'Keeping Up With The Kardashians' star appeared in court in Los Angeles this morning alongside his lawyer Robert Shapiro, who previously represented O.J. Simpson with his late father Robert Kardashian.

A source told gossip website that the 26-year-old reality TV star is now facing a trial for misdemeanour battery and petty theft but his high powered lawyer is famous for striking plea deals.

Rob was formally charged on Tuesday (07.05.13) after allegedly attacking a photographer and stealing her equipment in an altercation in Los Angeles.

The criminal charges come shortly after the alleged victim, Andra Vaik, filed a lawsuit for alleged robbery and assault over the row, which was sparked by her taking a shirtless picture of him as he worked out at the gym.

Andra's lawyer said last month: ''While this case is still in the preliminary stage, it is clear from our investigation that Robert Kardashian's violent behaviour and his use of force towards Ms. Vaik was completely unjustified.''

Rob - who has been struggling with his weight ever since breaking up with singer Rita Ora last December - insists the paparazzo was trespassing on private property in order to get a shot of him.

He says he was justified in snatching the memory card out of the camera, with eyewitnesses backing up his claim the photographer was lying in wait in her car in the garage at his West Hollywood gym.

Andra filed a robbery report at the time, despite Rob insisting he would pay her back.
