I’ll throw a vote in for her. Funny, too, because I can’t stand her…but I can’t deny the hotness.
Annie Lennox–specifically, as she appeared in the “Sweet Dreams (Are Made of This)” video.
Rawr. 
Butch Cassidy-era Robert Redford. Jude Law in The Holiday. As for the aforementioned Morena Baccarin…I would turn gay just so I could turn straight for her!
Like plnnr, my wife and I play this game often.
There’s no one I’d actually “go gay” for. But I can appreciate the aesthetical qualities of handsome men. But they give me more of a pause to admire them, and less of a hard on. I like beauty, but I don’t want to fuck a Rolls Royce.
Bono.
It’s got nothing to do with his looks, which are decent but not exceptional. Turn out the lights and have him sing to me.
You know, I’ve taken the tests, and the result is always “straight as an arrow, not a gay atom in your body”.
But if Daniel Craig came up to me and wanted to make out, I’d pretty much have to go along with it.
Gwen Stefani. And then we’d go shopping and buy fabulous shoes.
Oh, and even though Russell Crowe seems like a bit of a jerk, I sat through Gladiator in slack-jawed wonder at his sheer awesomeness. He probably doesn’t reach the level of making me question my sexual preferences, but… damn.
I’m as straight as they get, but I have a bit of a man-crush on Christian Bale.
I’m straight as a plank. I can look at a guy like Ben Affleck and say he’s good looking. But that doesn’t mean I want to have sex with him. It means I want to look like him so I could have sex with a woman like Jennifer Garner. I’ve honestly never felt a moment’s sexual attraction for another man.
Stephen Colbert. Without a doubt.
Bolding mine.
I’m sorry, but it’s just creepy to see this said about someone I remember as a kid.
I also felt a little gay after watching 300. I’m not sure if was any one of them in particular though.
Zebra, it was Gerard Butler. Now that is a slab of man-meat if I ever saw one. Rowr.
Who would I go gay for? Uma Thurman, definitely.
Maggie Gyllenhaal.
Natasha Henstridge. I’ve had a crush on her since Species.
Catherine Zeta-Jones.
I wouldn’t kick Keira Knightley out of bed, but I would make her eat a sandwich.
Gotta agree with this. While I may think Pitt or Damon or Clooney may be handsome or be in great physical condition I couldn’t imagine doing anything sexual with them. I like women and I like them XX, not XY with modifications. So even if Leonardo DiCaprio had reassignment surgery I still wouldn’t want him. Just not my bag, baby.
The first celeb I ever felt this way about was Madonna, back in the day, circa 1984.
Catherine Zeta-Jones is definitely my ideal, I just think she is the most gorgeous woman on the planet.
I have also felt the same about Selma Hayek, but since she got preggo by that creepy millionaire guy my crush has faded.
And, sure, I’d turn gay for Oprah, why not?! She could be my sugar mama!!! 
I can’t say there’s any celebrity out there whose looks would make me go gay. However, if I had to choose, I’d say Alton Brown. He’s funny and charming (even more so in person than on television), and he’d cook for me. Also, he likes to travel, and he rides cool motorcycles. Done deal.
And my wife wouldn’t kick him out of bed, either, so everybody wins.
