I saw "Pirates of the Caribbean: On Stranger Tides" this afternoon. Gemma was very mesmerizing when she was on screen, though it was sadly only for about 2 minutes. She was the first mermaid they show in the movie and was very strikingly beautiful. She also sings to enchant the sailors.
The pictures in post #3423 showing Gemma as a mermaid do not do her justice. They are nothing compared to seeing her in motion on the big screen. She really shines in the movie, and I am not saying that just because I am a fan of hers.
And for anyone who was wondering, Gemma's face is still just as beautiful as it always has been.
