I'm not convinced with her acting skills... she only had a mini role in the Pirates of the Caribbean movie... 5 minutes, a little bit of singing, looking good, flashing her vampire teeth (yes they had mermaids with vampire teeth ) and that was it.
Actually, she played in a couple other movies before Pirates of the Caribbean. Supposedly, acting and drama is a passion of hers, so I'm really happy that she gets a shot to it! Hopefully it'll lead her somewhere.
