Vin Diesel stumbled into the room, noticeably exhausted, dressed in a tan suit and striped untucked shirt, with a little afternoon stubble (on both his scalp and his face) and a sexy killer grin.

He explained his state of fatigue as he fell into a chair: "You arrive in New York at 4am and you have to be up at 7am to do all the TV interviews, and then you lie down at about 4:30am and you know you have to get up in about three hours. And you start to think, What the hell am I going to say on Letterman?"

The man was beat. But he looked good. And I know this because I couldn't stop staring at him, although I tried. I asked him if he'd figured out what to say on Letterman.

"I have no idea," he said, and smiled. Sigh.

I had been looking forward to this interview for weeks. It had been a long time since I had a huge crush on a movie star. With his macho persona, gravelly voice, sexy shaved head and edgy attitude, Vin was the man for me.
