Mark Wahlberg Wearing Short Shorts in Barbados

Mark Wahlberg is flirting with Speedo territory with his latest swimwear choice down in the Caribbean … because he’s wearing some seriously short shorts.

Check out this photo of Marky Mark strutting his stuff down the beach on the west side of Barbados on Tuesday … he’s rocking a pair of baby-blue shorts that are riding way up his thighs.

Mark is showing lots of leg here, and it looks like he doesn’t skip leg day … because the dude is absolutely jacked.

Photogs have been snapping lots of pics of Mark as he enjoys a tropical getaway with his wife Rhea Durham … and with each passing day, it looks like his bottoms get shorter and shorter.

Maybe Mark is waiting for the new year to bust out that Speedo … and you know the paps will be all over it if he does.
