Big Brother Couple to Headline The Amazing Race

Talk about two reality show extremes.

Former Big Brother contestants Rachel Reilly and Brendon Villegas -- dubbed Brenchel -- have done time being cooped up in the BB house to compete for cash. Now, the reality TV couple will be unleashed upon the world in the next installment of The Amazing Race, which premieres at 8 p.m. Feb. 19, Entertainment Weekly reports.

To refresh you: The cunning-but-obnoxious duo first met in the Big Brother house during season 12. They became targets after they coupled up, then backstabbed and bullied everyone in their path and both wound up leaving the show fairly early. However, they remained enough to prove that A)  they were both seemingly emotionally unstable, which B) made for GREAT reality TV viewing; and C) we hadn't seen the last of them.

After the show, Villegas (who is earning his PhD in physics) and Reilly (a chemistry major turned VIP cocktail waitress and two-bit soap opera actress) became engaged.

Then, Villegas and Reilly -- with her grating voice and voluptuous body, which was always stuffed into tank tops small enough to make Jenni "J-Woww" Farley proud -- returned to Big Brother during season 13, and Reilly went on to win the whole shebang.

Can Brenchel's reality reign last when they only have each other to push around and threaten? Will they be able to keep their emotional lunacy from bubbling over long enough to reach every pit stop? We'll find out in less than three weeks!
