How, you ask could I have not recognized a pop star of such renown? Of course I knew who she is. Who hasn't heard about the SNL lipsyncing fiasco? It got its own parody site and reactions from famous stars. It even got her an offer to come back to SNL and try again.
Still, the hair color change led me astray. She changed from a pretty blonde to a not so pretty Joan Jett imitator. I assume she is paying royalties to Ms. Jett for infringing on the look; now if she could only get a loan of the talent (of course I haven't heard Joan Jett in about 10 years - I am assuming there is still talent).
