Big Brother 13 - Duos - Spoiler

reality blurred reveals some spoilers that have come up recently for Big Brother 13 which premieres tonight.
The premiere is only a couple of hours away and there's a chance that the spoilers are wrong, but here goes:
The duos are: Jeff and Jordan, Brendan and Rachel... and Dick and Dani! (Source)
Another spoiler popped up later revealing that Dan and Memphis was a fourth duo being added to the mix. Two of the former contests have already been eliminated from the Big Brother House (I guess that's Dan and Memphis based on the other spoiler). This could be the "second twist". (Source)
Big Brother airs tonight at 9 PM ET.
