Could the reason behind Pam Anderson's quickie Vegas marriage be pregnancy?

That's the rumor coming from In Touch magazine, which claims that the "Baywatch" star is expecting a baby with new hubby Rick Salomon.

The magazine, quoting insiders, claims Pam is two months pregnant and that she almost called off the wedding after Rick spilled the baby beans.

But Pam's reps deny the story and point to her website, where she denies she's pregnant.
