She is cute, but I don't think those pics are from MET. I don't recognize her and the pics don't have the MET logo copyright on the bottom. MET always puts that on their released pics from as far back as I can remember (ie. 1999). Sometimes the host (teenfiles) uses other pics in an attempt to send the viewer to the referenced site(in this case MET) for credit.
If anyone knows different, please let me know.
