Aaron Rodgers and Olivia Munn have been dating most of the season, leading many Packers fans to speculate that Rodgers' MVP-level play is a result of his love life.

It's certainly not because of all the relations they're having on Sundays. Asked by Andy Cohen on Bravo's Watch What Happens Live about sex on Packers game days, Munn said it doesn't happen.

"No we don't. Not on game day," Munn said. "There's not a rule. It just doesn't happen because there's other things to focus on."

Munn's out here sacrificing -- and so is Rodgers! -- for the good of his team. Quite admirable. And Munn also pointed out all the "good-luck charms" for Green Bay are the fans and the players.

"I will say that all the good-luck charms are on the field and in the stands," Munn said. "So it has nothing to do with me."

But the whole no-sex-on-game-days thing isn't a superstition. It just doesn't happen.

"I try to have sex as much as I can," Munn said.
