It may be November, but the temps in Southern California are still in the low 80s, so until fall actually hits us, Hollywood types like Eddie Cibrian will be showing off their guns in tank tops!

Yesterday LeAnn Rimes' hunky hubby hit the gym in Calabasas, and he flashed us a peek at his buff bod before hopping in the car. While he seemed to be in a reasonably good mood, rumor has it he's been keeping a low profile to hide an affair!

"When things were great with LeAnn, Eddie would always chat and wave to the photographers outside his house," according to a source for Star Magazine. "But now he’s trying to hide. He’s doing everything he can to avoid being spotted." Seeing as LeAnn and Eddie both cheated on their respective spouses to be together, this wouldn't exactly be a total shocker, but still!
