Oh, Lordy! You've got some nerve, girl!
Rob has been seen wearing the blue hat on several occasions through the past couple years, but KStew took things to a whole new level when she was seen wearing the same one less than two weeks ago - WITH the guy she was cheating with!
Shaking our heads….
Apparently, Kristen was trying to stay incognito while she and good ol' Rupe were driving around El Lay looking for secluded places to make out.
In fact, a source adds:
"[They] would only take a break when they thought someone was walking by. It seemed like they couldn't get enough."
As if our poor little Patzy-Poo hasn't been through enough! Way to shove it in his face!
