Claim to fame: With her second pop-rock album, M!ssundaztood, Pink marked her departure from her original R&B image. She even took shots at L.A. Reid in "Don't Let Me Get Me." Since then, she's had enough successes to put out her most recent Greatest Hits...So Far!!! album. Yes, fortunately, she didn't get dropped from her label after those shots; maybe it's because she looks like she'd beat someone's ass.
