Sha'Carri Richardson won't be running to the "Big Brother" house any time soon, cuz reports the one-time Olympic favorite is joining the show's cast just ain't true ... TMZ has learned.
The American track superstar's name flooded "Celebrity Big Brother" message boards and then hit outlets Wednesday reporting she'd be an upcoming contestant on the popular show.
Unfortunately for Sha'Carri fans, the reports just aren't true ... her rep, Ashley Blackwood, tells TMZ, “Sha’Carri was contacted months ago to be on Big Brother and declined. All coverage on her participating are false and simply just rumors.
