One of the houseguests entering the Big Brother 17 house is already a millionaire, and will certainly be recognizable to many.

Will 'Big Brother 17' Feature The Show's First Ever Transgender Houseguest?

Vanessa Rousso, one of the most well known poker players, is part of the new Big Brother cast. The 32-year-old, who is ranked as the no. 2 female poker player in the world, has earned $4.5 million in her career. As noted by BLUFF, her biggest single score was at the 2009 EPT Monte Carlo Grand Final High Roller where she earned a pretty penny: $962,958.

The $500,000 prize for winning Big Brother is nothing compared to what Vanessa has earned over the course of her career, but that won't stop her from playing to win.

One thing that may set Vanessa back is the presence of another houseguests, Da'Vonne Rogers, who is actually a poker dealer. It seems likely that Da'Vonne will recognize Vanessa right away, and this could put a target on the latter's back if the other houseguests know she doesn't need the money.

Vanessa's ability to read others, strategize and literally bluff may serve her well in the game of Big Brother. The show is ultimately a mind game when it comes to forming bonds and knowing when to cut people, so if Vanessa brings her cutthroat nature into the game she could be very dangerous. It could also make her a huge target in the game.

Big Brother 17 premieres on Wednesday, June 24 at 8 p.m. ET/PT on CBS.
