Uh-Oh! It's looks like Rihanna's new album 'Unapologetic' has sprung a leak. First, we heard Rihanna and Chris Brown's infectious duet 'Nobody's Business' and now we get another collaborative smash with her destined club hit 'Numb,' featuring Eminem.

Rihanna has teamed up with Em before on the chart-topper 'Love the Way You Lie' and it looks like the dynamic duo may repeat that same success with 'Numb.' The song is a little controversial because it's an ode to feeling "numb" after taking drugs (or, metaphorically, after listening to Rihanna's music). Peep Ri-Ri's first verse, "Ecstasy in the air / I don't care / Can't tell me nothing / I'm impaired / The worst for wear."

The song bumps along on a slow groove of an Egyptian flute riff, a crashing bombastic beat and a warped sample from Kanye West's 'Can't Tell Me Nothing' ("Let the champagne smash / Let that man get cash").

But it's Eminem who steals the song from Rihanna with his tripped-out lyrics. He spits, "Yeah, yeah, yeah, come here dear / Trying to get closer to you / I'm motioning you to pull over boo / I'm the siren that you hear / I'm the butt police, and I'm looking at your rear, rear, rear." Call the police, we think this a murder rap.

While this may be an homage to getting high, you will feel numb with aural pleasure after listening to what we believe is going to be a big hit for Rihanna. Go ahead, get 'Numb.'
