You didn't misreport. She "was" a dancer at one time.
From the Telegraph: Costa Concordia: operation complicated by unregistered passengers - Telegraph
"Miss Cemortan, who works as a translator for Costa cruises, but was traveling on board as a passenger at the time of the disaster, has denied that she and Schettino are lovers. "
All reports I've read say the same thing. She had
been a dancer but was currently working as an interpreter. On this voyage she was just getting a ride.
