If you haven’t been able to keep count on who is the biggest hobag on reality TV,
MTV’s Web site posted an official hook up chart to fill you in.

And the person with the highest number of reality star-to-star hookups happens to be Real World: Sydney’s Kellyanne (above)–who has been certified by MTV as the sluttiest cast member for having bumped no-no parts with five other male MTV stars.

From MTV:

Quick disclaimer: We’ve done the best we could, but mistakes are inevitable. The more speculative hookups are outlined in red, but we’re not willing to bet our lives on any of the black-lined ones, either. Our point? Take this all with a grain of salt, and believe what you want

The Web site admits a few omissions, so I started my own list after the jump — please feel free to correct me/make additions.

Other hookups:

Road Rules Semester at Sea’s Veronica – Eric Nies
Mark Long – RW San Diego Robin

And as a bonus, all of this nostalgia reminded me of my FAVORITE drama queen Ayanna and her epic fight with Veronica. So I’ll leave you with the clip. Enjoy:
