Though I haven't seen her do much outside of Nickelodeon she seems like a decent girl.
I barely remember her on Drake and Josh (hated the show so I didn't watch much), her character was a heartless bitch.
Ironically her character Carly on iCarly was very sweet. I really like iCarly, very good writing, and I'm not afraid to admit it.
I'm also not afraid to admit that she's a decent singer. Didn't even know she sung until some DJ mentioned her name on the radio after one of her songs played.
The media (and myself included) kinda went hard on her for falling out of the spotlight and going into rehab for "reasons unclear", but I still love her.
I've heard of her before, but never payed much attention until I watched Sonny with a Chance with my girlfriend.
His political shows are very funny and insightful. I can even forgive him for pretending to be a Libertarian. He's a social-Libertarian yes, but I would never associate myself with the psychopathic and delusional anarcho-capitalists.
