The owners of sports betting website are so convinced that Beyonce Knowles is pregnant with her first child, they're refusing to take bets on the fact.

Instead, the site is offering odds on the sex of the child.

But the singer's publicists insist gossips are reading too much into Knowles' decision to pull out of a couple of upcoming, high-profile events.

Spokesman ALAN NIEROB says, "I've received a lot of calls asking if Beyonce's pregnant and if she and Jay-Z are getting married. The answers are 'no' and 'no'."
