The time has come to take a pilgrimage to Bachelor Mansion, otherwise known as the House of Lies that Desiree Hartsock has been living in for the past several months. Yep, there are traitors among us, everyone! One of Desiree's contestants on The Bachelorette has a secret girlfriend, so you can go ahead and clutch your pearls.

In this new promo from People, we see Brian Jarosinski's girlfriend, Playboy Playmate Stephanie Larimore, show up on set and introduce herself to Des. That's right, Brian had the nerve to come on The Bachelorette despite being in a relationship! Unacceptable.

Desiree's reaction to this sordid betrayal? Unclear. Despite the fact that People's promo shows Des saying “Are you guys here for the right reasons?” before cutting to footage of Brian's gal pal, we have yet to see this Bachelorette's real reaction. According to Reality Steve, Des asked this question during her first group date, when she forced her hunks to make a rap video with Soulja Boy called “Right Reasons.” See? ABC's misleading editing skills have struck again!

Either way, it looks like Brian is already defending himself for showing up to Bachelor Mansion as a taken man. And because he seems to be all about the PR (and working out and tanning on rooftops), he used his Twitter to tell who he really is (in 140 characters or less). "Those who try and attack your character are nothing more then [sic] extra motivation," he tweeted cryptically on May 10.

Whatever, Brian. No scrubs. Go back to the Playboy Mansion where you belong, sob!
