Sammy Hagar truly has had The Best of Both Worlds. Or so he claims, anyway.

The former Van Halen frontman is out promoting his new memoir, "Red: My Uncensored Life in Rock," a rollicking tale that focuses on groupies, sex tents, cocaine and, of course, hair metal. But in an interview with MTV, Hagar discusses a topic he largely left out of the book -- one that makes sex with eight women at a time seem minor, at best.

As it turns out, Sammy Hagar has been abducted by aliens.

"Remember the story in the book, where I have a dream about being contacted by aliens in the foothills above Fontana?" he asks the MTV interviewer. "That’s right. It was real. [Aliens] were plugged into me. It was a download situation. This was long before computers or any kind of wireless. There weren’t even wireless telephones. Looking back now, it was like, 'F**k, they downloaded something into me!' Or they uploaded something from my brain, like an experiment. “'See what this guy knows.'”

Perhaps they were after his knowledge of sex tents. And fine restaurants. After all, in the book, Hagar says, "I was eating in the greatest restaurants, drinking the finest wine, flying on private jets, walking on stage to sold-out audiences going crazy. The only thing missing was ... I don't think anything was missing."

But then again, this wasn't the first close encounter that Hagar says he experienced.

"That happened. That friggin’ happened, I’ll tell you right now," Hagar continued. "Another thing happened when I was about four that I didn’t put into the book. One time I saw what I considered to be, well, at the time I thought it was a car with no wheels. We lived out in the country and I saw this thing floating across a field, creating this big dust storm. I threw rocks at it and shit. And I don’t know what happened after that."
