True, it's the type of thing we should know given the nature of the job, 'n stuff. Either we're not very good at our jobs (stop) or Sandra Vergara has been keeping a very low profile... as it happens, she hasn't been. Sandra is also an actress - she's been in Fright Night, an episode of CSI, and more recently has a recurring role in soap The Bold and The Beautiful. Nothing wildly notable when compared to Sofia's run... hence why Sandra's possibly turned up in a fishnet dress to the 2014 Hamilton Behind The Camera Awards on Sunday.
Sandra - who's technically Sofia's cousin who was then adopted by her mother when she was 1-month-old (see, we know stuff) - is no stranger to the red carpet, appearing at several events over the last couple of years.
Watch this space... unless she's really bad at acting... either way, she seems very sound and not adverse to nudity.
