Trouble tends to follow Rob Kardashian. The lone boy of the Kardashian clan is being sued for alleged robbery and assault of a photographer.

According to MSN News, Andra Vaik claims the assault occurred when she tried to take a shirtless picture of Kardashian.

Kardashian, allegedly, assaulted the female photographer and stole parts of her camera's equipment during an outing last month.

The 26-year old "Keeping Up With The Kardashians" star, reportedly took the memory card from the camera.

TMZ caught up with Vaik's lawyer to discuss the reports filed. 

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

Kardashian alleges he lashed out because Vaik used illegal tactics to photograph him. He said the photographer trespassed on private property to get a shot of him shirtless, TMZ reported. 

Witnesses told the news site that the photographer tried to get photos while inside of her car, parked inside the garage of the property.

Many fans will recall another one of his public tirades, while bashing ex-girlfriend Rita Ora on Twitter.

Rob tweeted, "She cheated on me with nearly 20 dudes while we were together, I wonder how many she will sleep with now that we apart? (sic) But I mean 20?!!!"

He continued, "How can a woman who is so busy trying to start her own career have time to be with so many dudes all while in a relationship?!"

But with the past behind him, the reality star seems to be focusing on his personal goals.

According to the Daily Mail, Kardashian is in the middle of a strict weight loss regime and is trying to lose an extra 40 pounds.

"It's a little journey, but it's good... I'm like 240lbs right now, probably 235lbs," he said.
