Jayde Nicole -- I'm No Las Vegas Whore!

Jayde Nicole is being touted around Las Vegas as a full service escort who will come straight to your hotel room if the price is right. Problem is, Jayde knows nothing about it.

TMZ has learned Jayde's image is being passed around Vegas on those escort-for-hire cards that those people flick at passersby on the streets.

On the flier, Jayde is identified as "Tanya" -- and the accompanying nudie pic is ripped straight from her Playboy spread.

But here's the best part: We called the escort service -- strictly for research purposes -- and they guaranteed the woman you saw on the card is the same exact woman who will show up to your sleazy motel room.

They also explained that "Tanya" doesn't cost $35 -- but if you turn in the card, you get a $35 discount from the regular price. Sorry ... they wouldn't tell us what price is regular.

But obviously, Jayde is not really a Sin City streetwalker -- and now a rep for the former Playmate of the Year tells us lawyers have already "dispatched a cease and desist letter" on behalf of both Jayde and Playboy.
