This week, The Secret Life of Siegfried and Roy comes roaring (ha!) out of the closet and into the book stores. The story of tiger-taming Roy Horn and his "business partner/lover/brother" (eww?) Siegfried Fischbacher was written by the Las Vegas acts' former head of security, his son, and one of the duo's consultants, and typed up by the VP and senior editor of the publisher, Phoenix Books, which also published Train Wreck, the biography of Anna Nicole Smith. It is remarkable! Not least because it renders the tiger-tamers' thoughts in a strong accent. (Seriously: "Siegfried's mind raced. No vun realizes vot the tigers are capable of, he thought.") Here's a particularly stellar excerpt that answers the question on everyone's mind: Did they ever actually sleep with women? And what would that mean?

Even though they're officially out of the closet, Siegfried and Roy's sex lives remain impenetrable which is just the way they like it. There are rumors galore about their relationship, and whom or what they bedded. Ironically, each maintains a separate bedroom for the other in their respective homes to this day. But when Siegfried eventually moved into his own abode in 1996, the duo's personal relationship had already been rocky for a while. At this time, their on-again-off-again cycle apparently went off-again, even though their working partnership continued.

As with any marriage, it's nigh-impossible for an outsider to guess at the nature and frequency of sexual activity, or if it even exists—and whether both parties involved are being faithful to each other....

It's interesting to note that, of the two, Siegfried had the bigger reputation for promiscuity. The staff joke was that he'd screw a doorknob if he thought it might respond. And the really intriguing staff rumor about his rampant ways is that Siegfried has a child out there somewhere! (Maybe more than one.) Be that as it may, and notwithstanding speculation about intercourse with doorknobs, Siegfried himself has let one rather big cat out of the bag—he admits he's slept with women. Which makes the "baby Siegfried" (or "Siegfrieda") rumor possible, but still unconfirmed.

It should be noted that female fans—who always reacted to the lads like they were rock stars—often made it screamingly clear that they'd love to graduate to groupie status ... and get a peek at what's under those trademark codpieces the duo wear onstage. Whether it's beamed at women or men, Siegfried and Roy exude a fierce sexual power.

Has Roy slept with women? Absolutely. Does this mean he and Siegfried are bisexual? Not necessarily. Insiders say beefcakes, not cupcakes, trigger their sexual appetites. Their rare physical couplings with women are simply a way for the power-hungry Germans to exert control. Roy's been described by observers as an octopus with many tentacles, manipulating and demanding extreme perfection from everyone, himself included.
