‘Big Brother 17’: So Many Twins, So Little Time [Photos]

Big Brother victory is achieved through alliances, competition, prowess, and lies. Fans of Big Brother 17 know that at least one houseguest is carrying on a significant ruse. That houseguest is actually a set of twins, playing as one person. If they can make it through five evictions, they enter the house as individual players.

Big Brother announced the twist as part of the two-part premiere last week. The show has not disclosed which of the players is swapping out with her sibling. Bloggers have deduced it must be Liz Nolan, who sometimes models with her twin sister Julia. Fans were quick to point out that Liz and Julia don’t look exactly alike, although they are very similar.

But is it Liz and Julia?

Shelli Poole told the houseguests she has a fraternal twin brother. No one in the house questioned whether she was telling the truth. This week, a Shelli Poole fan Twitter account posted what appears to be a family photo.

Let’s play a game! Guess who’s Shelli’s fraternal twin is #BB17 pic.twitter.com/3XkRtjov3c

The caption does not say that Shelli herself is in the photo. So the conspiracy theorists may say that the woman that looks like Shelli in the photo is in fact her twin sister. But if Shelli is swapping out every so often with her twin, she’s playing a dangerous game, as she continues to flirt with Clay.
