Rihanna has abruptly canceled her planned performance tonight (Feb. 8) at the 51st annual Grammy Awards at Los Angeles' Staples Center, according to an announcement from the Recording Academy, which did not provide further details.
Al Green, who won two R&B Grammys during the pre-telecast, replaced Rihanna in the lineup in a performance with Boyz II Men and Justin Timberlake.
Speculation is rampant that the cancellation is connected to an incident that occurred early this morning involving Rihanna's boyfriend, R&B star Chris Brown.
The Los Angeles Police Department was seeking Brown on a domestic violence felony battery report after he began arguing with the unnamed passenger in a car, said to be Rihanna. The argument escalated after they exited the vehicle but Brown wasn't at the scene by the time police arrived. Brown turned himself in to authorities around 7:15 p.m. PT.
Rihanna performed early this morning at Timbaland's pre-Grammy party. For Billboard.com's Grammy microsite, please click here.
