George Clooney is all praises, and even in awe of her beauteous co-star Sandra Bullock. So how come they never dated? Clooney spills the reason, as well as his worst movie costume.

In an interview with MTV, George Clooney, star of "Gravity" was asked on which was more uncomfortable, his space suit or the Bat-suit in "Batman and Robin?" Without batting an eyelash, he replies: "Bat-suit. Let's face it: the space suit was just uncomfortable for me, the Bat-suit was uncomfortable for all of the world."

On an actor's worst nightmare: "Pretty much wearing a Bat-suit. They put nipples on the damn thing. I didn't even know it until the film came out. You can't bend like this when you're Batman."

On why he accepted "Gravity despite the tedious special effects and costume(space suits): "Being there with Sandy [Bullock] made it really fun.  We were old, old friends, we've been friends a long time. It's fun to be around her, it's fun to watch what she's become over the years."

Speaking of Sandra Bullock, he was asked on a separate interview on E! News about why they didn't date. They were at the NY Premiere of "Gravity" and Sandra Bullock was strutting down the red carpet.  "She was dating one of my best friends,"

But...why not now then?

"There's a certain bro code, you know what I mean?" he insisted. "I've known her a long, long time. She looks beautiful, doesn't she?"

On what he's looking for in a girl: "I don't know what qualities I would look for. I'm looking at Sandy there and you're asking me questions like that!"
