According to an old-ish interview that was dug up by Queerty:
"I talk about my sexuality, but it’s always glossed over. People seem to shy away from the issue. Whenever it is discussed, its distended and exaggerated. Gerard Butler is gay. No I’m not. I don’t know myself what I am so it can be bewildering to see that being plugged. I have been in relationships with women. And men. That doesn’t make me gay. That doesn’t make me straight." — Gerard Butler
Yes, but did the 300 and Phantom of the Opera star REALLY live dangerously and date Jennifer Aniston?? Everyone knows how clingy and needy Jenn can be. In fact, I hear she requires a marriage proposal and a "JA4Ever" tattooed on your ass after the 2nd date...
Dating men? ... No big deal. Dating Aniston?... Now THAT'S scary!
