I looked up Carly Smithson. Can't be. Eyebrows are totally different and Carly has a much sultrier/sexier look than this "mentally handicapped stroke victim" smile this girl has. Also note the lack of tats on her right shoulder/arm.
Carly also has hypnotic, deep, blue eyes. This girl.... not so much.
I can't say one way or the other, but eyebrows are fixable and Carly didn't have the tats back when she was Carly Hennessy.
The top pic does remind me of somebody (not Carly) but I can't remember who it is.
