Miss Colombia: Mega Porn Offer ... Choose Your Sex Partner and Make a Million

Miss Colombia could become the biggest thing in beauty pageants since Vanessa Williams ... if a porn king has his way.

Vivid honcho Steve Hirsch

to Ariadna Gutierrez Tuesday offering up $1 million. He made his case with another famous pageant queen, writing, "The only name that most people remember is Vanessa Williams," adding the reason for her rise to fame was nude pics in Penthouse.

Hirsch goes on with his pitch ... "Celebrity sex tapes we have distributed have enhanced the careers of stars such as Kim Kardashian, Kendra Wilkinson, Pamela Anderson and many others."

And Hirsch is willing to give Ariadna wide berth, saying, "You will pick your partners, the type of sex you want to have and how many movies you ultimately appear in."
