It seems life finally takes its toll on Chris Brown, as the 23-year-old star was snapped whipping off his shirt and grabbing his crotch infront of the paparrazi in Beverly Hills.

Wearing nothing but a pair of grey shorts, showing off his tattooed chest, Brown glared at the photographer and made the gesture before getting into his SUV and driving off, as if trying to make a point.

The crotch grab follows a tough week for Brown, as the singer recently got involved into two fights--one with his longtime bodyguard and another with a valet outside a charity event.

Reports say that Brown allegedly ditched his bodyguard Big Pat at the airport in Bermuda after an apparent argument, leaving him to make his own way back to the U.S.

"I'm not sure of the details of what happened on the plane, but his plane came in, got serviced and everything was finishing and they were getting ready to leave. Then there was a stall. The security guard got off first. He was standing outside talking to the pilot. Then Chris Brown and another guy came off," an airport worker told Bermuda Sun.

"They then went outside to have a cigarette. The security guard came inside (the airport building) and said he wasn't getting back on the plane... Chris went back through Customs and the plane left at about 2:20 p.m.," he explained further.

Meanwhile, just days later, the R&B singer was caught on video throwing F bombs to a valet parker outside a Los Angeles bowling alley, in what was an apparent disagreement over the $10 parking fee. Brown was allegedly angry because he had only been inside for 30 minutes and didn't think he should pay.

It was indeed a rough week for Brown. This is not to mention Rihanna being away for her Diamonds world tour, which probably also added to the stress and frustration of the Don't Wake Me Up singer.
