Taylor Swift and Travis Kelce ... reality TV superstars??
HIGHLY unlikely ... but if the pop singer and Super Bowl champ ever welcomed the cameras to document their every move, it would become the "biggest reality show ever" -- so says ex-NFLer and "Baller Wives" star Channing Crowder, who tells TMZ Sports the entire planet would tune in!!
"Taylor Swift is worldwide," the former Dolphins star said. "Most reality shows are national. This would play in Australia, this would play in the damn North Pole and everywhere you wanna say -- India, Egypt.
