With the "Twilight" saga set for its Part 2 release of "Breaking Dawn," many of the twi-hards are scouring for the latest and juiciest up-to-date information on its stars. However, many will be more shocked to hear what is going on off the set and in between the sheets of high profile couple Robert Pattinson and Kristen Stewart's relationship. 

It is reported that the gossip flood gates will burst open as the "Twilight" star duo and their sexual escapades are said to be soon revealed in a juicy tell-all, according to OK! Magazine. 

The source claims that the "One big topic will be how they first got together. Rob basically stole Kristen from his first love, Michael Angarano, and used cast mate Nikki Reed along the way. When Rob saw he couldn't have Kristen he went for Nikki - but he never stopped pursuing the lady he really wanted."

Supposedly it was not until the "New Moon" sequel that Rob and Kristin started to get intimate, which did not sit well with his ex-Reed, who plays Rosalie Cullen.

"It was a bit sad because Kristen and Nikki started out as really good friends, but then because of Rob they ended up hating each other," said the source, according to OK! Magazine.

The OK! Magazine source also added "They are very liberated sexually - there were even suggestions that they were in an open relationship, so that could come up."

Not exactly denying the accusations about their wild sex life, Stewart recently came clean that the couple indeed lost themselves while shooting the sex scenes for "Breaking Dawn Part 2."

I got three words in response to this one:  Get A Room!

Or better yet, a really fancy expensive suite.
