Ugly Betty executive producer Salma Hayek, who thus far has only been seen in the background on the ABC comedy's telenovela-within-a-show, will appear in a four-episode arc beginning with the Nov. 2 episode. Hayek will play Sofia Reyes, a newcomer to "Mode" who will leave a lasting impression on Betty and Daniel. (As she should, being the one who signs their paychecks and all!)
