Sources close to the production of ‘Amazing Race‘ told TMZ … the show reached out to several past “Big Brother” houseguests and has locked down its list of competitors for the new season, which will begin filming soon.
We’re told the all-“Big Brother” edition of ‘Amazing Race‘ will feature at least one past ‘BB’ winner, but several other popular winners declined for family or career reasons. Still, we’re told CBS is happy with the final cast … and they’re ready to race around the world.
