got off on a bumpy start for Chris Brown
The best urban contemporary album nominee walked away uninjured after crashing his black Porsche into a wall during a paparazzi chase.
Beverly Hills police tell PEOPLE the accident occurred Saturday around noon when Brown, 23, lost control of his vehicle while driving to an L.A. charity event.
After Brown was reportedly cut off by photographers, "the occupants jumped out, with cameras, and aggressively approached his vehicle," Brown's rep said in a statement, via Entertainment Weekly
. "In an effort to remove himself from the situation, he began to back down an alley, at which point he was cut off by two additional vehicles."
According to his rep, his car was totaled because of the "aggressive pursuit by paparazzi" but "he is okay." The Porsche was towed away from the scene upon Brown's request, the police tell PEOPLE.
However, the photo agency responsible for the photographers on the scene are refuting Brown's story, saying that the paparazzi didn't arrive until after the accident. Chris Doherty, owner of INF, the photo agency, tells TMZ
that his photographers "had nothing to do with the Chris Brown crashing" and that it's simply "convenient for him to blame us."
Lt. Lincoln Hoshino said authorities will investigate the incident, although he didn't know whether any of the involved parparazzi have been identified, according to an Associated Press report.
It's been just four years since Brown first caused a stir during Grammy weekend as a domestic violence drama
began to unfold between him and on-again girlfriend Rihanna
right before the 2009 awards ceremony. Now, fans will wait and see if the two attend this year's show together.
A call to Brown's lawyer by the AP was not immediately returned.
