Melissa King -- Miss Delaware Teen USA Offered $250,000 Porn Contract

She might have lost her crown ... but former Miss Delaware Teen USA Melissa King has just been offered a pretty sweet back-up plan ... $250,000 to promote a hardcore porn site.

As we reported, 18-year-old King resigned yesterday after a porno surfaced that allegedly featured King doing the dirty ... just months before she won the title last November.

Now, porn giant YouPorn.com wants to compensate her for the unfortunate situation -- offering to crown King the first ever "Miss YouPorn" and pay her $250,000 to tour the world promoting the website.

Funny enough, YouPorn's offer -- which was submitted to King yesterday -- doesn't mention having sex on camera in exchange for the fee. Not a bad deal.
