Fiona Xie + Transformers = Nosebleed!
Boss showed me the 25th June 2009 issue of iWeekly. It has local TV hottie Fiona Xie on the cover. Inside the issue, there are more photos of Fiona posing with Bumblebee and Optimus Prime! Pics so smoking hot that I had to scan them for your viewing pleasure.
You can view the high resolution scans on my Flickr photoset here. Btw, the Transformers costumes were from Movie Mania.
