it is a mystery, Mexican magazines especially still love Cindy - we all remember the Marie Claire Mexico photoshopgate incident. Perhaps because Cindy had the standout global crossover appeal in the 80s/90s readers still have fond memories and want to check in with her?
That being said, HB Mexico always has kind of unexpected cover stars. We've seen cover stars as unconnected as Shakira, Lindsey Wixson, Olivia Palermo, Jessica Hart and Salma Hayek all in the past year!
