A month after Rihanna confirmed her first live performance since the February altercation with boyfriend Chris Brown, the 21-year-old R&B star has cancelled the May 28 Dubai show.

This week, Eminem's new single, "3 A.M.," leaked -- as did a teaser video for the gory song, along with more details about his May 19 record, Relapse. Meanwhile, SPIN reviewed Green Day's 21st Century Breakdown (May 15), as the band defended their classic-rock ambitions and punk rock roots.

Chris Brown's lawyers are working every possible angle on behalf of their client.

In addition to reportedly pursuing a plea deal, Brown's attorney Mark Geragos is prepping an argument for the singer's case to be dismissed on the basis of "leaks" about the trial.

Rihanna is currently in the studio recording her next album -- and according to her producers, Norwegian duo Tor Erik Hermansen and Mikkel S. Eriksen, the troubled pop starlet is ready to prove her musical mettle.

This week Green Day gave lucky fans a sneak peek of their summer tour, Jack White's new band, the Dead Weather, debuted live, Rihanna planned her comeback, and Phil Spector was convicted of murder.
