One of the tour buses of Canadian rapper Drake was robbed on Tuesday while he was performing on stage with fellow rapper Future in Arizona.

Gossip website TMZ obtained a video of an upset Drake after finding out about the theft, throwing his hands in the air in disbelief. The website reported that the thief or thieves stole a briefcase inside the bus.

The contents of the briefcase contained bling that is reportedly worth between $2 million and $3 million dollars. Although the briefcase belonged to his DJ Future the Prince, that didn't stop Drake from being upset about the heist.

"Their bus was parked in the lower garage," the police said, according to Entertainment Tonight Online. "Between 10:00pm and 10:15pm, a suspect boarded the bus and removed a briefcase containing an estimated $3 million in jewelry and property."

Detectives are currently conducting an investigation, and are currently reviewing surveillance tapes from the backstage area. It is being alleged that the theft was an inside job, most likely done by someone who worked at the Talking Stick Resort Arena, where the concert took place, and had access to the bus, according to Wonderwall.

The incident comes after the rapper has been enjoying his time with girlfriend Rihanna after the two finally confirmed that they were dating. The couple have spent the entire week showing some public displays of affection towards each other.

The singer also had a tattoo of a shark that was inspired by a date that she and the rapper had. It came days after he professed his love for her while he presented her with the Video Vanguard Award during the MTV Video Music Awards on August 28.

"She's someone I've been in love with since I was 22 years old," Drake gushed about Rihanna. "She's one of my best friends in the world."
