"Big Brother" Rachel & Brendon Join "Amazing Race' Cast!

They're baaaaaaaack!

America's most hated reality TV couple, "Big Brother" winner Rachel Reilly and fiance/fellow Houseguest Brendon Villegas, are returning to the small screen.

This morning, the duo was announced as one of the 11 teams on the 20th season of "Amazing Race" -- which also includes hot twins, border patrol agents and married clowns.

This time around, the contestants will race through 22 cities and 40,000 miles -- including stops in Paraguay, Azerbaijan and the German castle that served as inspiration for the one in "Sleeping Beauty."

The show, which has won the Emmy for Reality Competition 8 times in 9 years, returns Sunday Feb 19 on CBS with host Phil Keoghan.
