Olivia Munn doesn't have sex with Aaron Rodgers "on game day."

Asked if she is the NFL star's lucky charm, the 34-year-old beauty told 'Watch What Happens Live': "I will say that all the good luck charms are on the field and in the stands so it has nothing to do with me."

Olivia insists she and Aaron don't have "a rule" about not getting intimate before he plays, but admits it never happens.

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

The actress, who started dating Aaron, 30, in April, recently admitted she has turned down acting roles so she can spend time with him in Wisconsin because she wants her "life to be full."

Discussing how they juggle their relationship and careers, she said: "You make decisions because it can't all be work and it can't all be your personal life, especially when you've worked so hard to have a career.

"There's a lot of travelling, a lot of driving, and then you're just really happy with the decisions that you make. And for me, it comes at a time in my life when I end up having to say no to some work because I gotta be somewhere else."

The couple started dating shortly after Olivia split from 'RoboCop' actor Joel Kinnaman after two years together.
