Have you heard that 90210 is back on? There's probably like so many life lessons being learned through that show. It is also a place where bands like N.E.R.D. play at random ass parties for teens to smile at each other at, as the video above proves. The band plays a new song tentatviely titled "Radio (WTF)," and it marks the television debut of new member Rhea, who raps at least as well as Pharrell. [NahRight]
