Justin Biber robbed! During a tour stop in Johannesburg, South Africa, Justin Bieber's $330,000 concert cash was stolen. The perpetrators are said to have had executed an elaborate 'Oceans 11' plan.

Justin Bieber's $330,000 was stolen this past Mother's Day, THR reports during his tour stop in Johannesburg, South Africa.

While Justin Bieber was serenading young girls during the show, the suspects reportedly used a scheme right out of movies, like Ocean's 11, using ropes and chisels to lower themselves into the safe room at FNB Stadium.

The stadium management team didn't learn of the Justin Bieber robbery until the day after the show. FNB stadium has been on lock-down while police, forensic experts and security company officials investigate the robbery where $300,000 was taken from the twee pop star, Justin Bieber.

After TMZ wrote about the story, Justin Bieber tweeted at them saying "It wasn't me."

Bieber's "Believe" Tour, which started in September of 2012, in Arizona, has been full of crazy events while he's been touring the world since then, running into questions of marijuana use, a monkey that was taken form him and an on-again off-again on-again relationship with now-ex-girlfriend, Selena Gomez.

But Justin Bieber robbed of $330,000 this past weekend might be the craziest addendum to an already insane tour.

The robbers reported chiseled through a wall to get to the safe room, ABC News reports, before lowering themselves down using a complicated system of ropes and pulleys harkening the famed Ocean 11 film starring Brad Pitt, George Clooney, Don Cheadle and others.

"It wasn't an impromptu incident," Jacques Grobbelarr, a member of the stadium's management team, told Eyewitness News South Africa.

"There was definite planning. Looking at the scene and the place they broke into, it looks as if they were planning this for quite some time, probably a couple of days."

Several employees have undergone polygraph tests as it's believed only people with intimate knowledge of the FNB venue could have pulled off the Justin Bieber heist. Bieber was performing in front of a crowd of 60,000 while the robbery took place, after Jon Bon Jovi had performed at the stadium the night before.

The suspects in the Justin Bieber robbery are still at-large as the police try and find the brazen culprits.
