GEORGE CLOONEY's longtime girlfriend SARAH LARSON opens up in the upcoming issue of Harper's Bazaar about how she met the Sexiest Man Alive, their reality show guilty pleasure and her many adventures with Hollywood's biggest movie star.

Sarah says she first met George about four years ago while working at a Las Vegas resort, when she was attached to someone else.

"We were hanging out and dancing and being goofballs," she says in the issue, out May 20. "Nothing crazy. We talked, that's it."

But things got serious in June of 2007 when they ran into each other at the premiere of 'Ocean's Thirteen.'

"I got texts, and we just started talking," she says. "George is funny and sweet, and he's good to be around," she goes on. "I see him as a normal person, like anyone else. He just happens to have a well-known face."

And the former reality show star, who once ate bugs on "Fear Factor," admits she doesn't know if she would have given even George Clooney a second thought if he had been on a reality show himself.

"If George had been on a reality show, I don't think I'd have talked to him," she confesses. "It would have been like, 'That's nice.' I don't know. He still wants to date me, and I ate a scorpion."

It's safe to say Sarah has come a long way from chowing down on creepy-crawlies. The waitress-turned-reality-show-star-turned-model -- who once studied microbiology -- has been keeping busy globetrotting with her Oscar-winning beau everywhere from the Academy Awards ("It was like a modeling job -- smiling and greeting people," she says) to Rome for the World Summit of Nobel Peace Laureates, where she met everyone from the DALAI LAMA to MIKHAIL GORBACHEV.

But that doesn't mean it's all red carpets and meetings with world leaders for the couple, who do normal things -- like watch marathons of "Rock of Love With BRET MICHAELS," which they did while recovering from their motorcycle accident last September.

"We caught ourselves rooting for someone or getting frustrated," Sarah says. "And we were like, 'This is sad.'"
