my faves listed

Voted for

Rih (she gives no ****s)
Miley (open about everything, and I respect her for that)
Gaga (has her moments of pretension but I think she's generally open and honest about things, especially recently)
Britney

I think the least open is Lana, but it's part of her character.

Lady GaGa she's true to herself and what she does and she's nice to fans. No other pop girl stops for their fans. Also Lana.

Mariah, Gaga, Britney and Miley all strike me as very genuine.

Lady Gaga
Taylor Swift
Beyoncé
