Escort Katina Powell says she has no proof that Louisville coach Rick Pitino knew that a former Cardinals staffer hired her and other dancers to strip and have sex with former recruits and players.

But Powell said Tuesday on ABC's ''Good Morning America'' that with ''a boatload'' of recruits and dancers, ''loud music, alcohol, security, cameras'' in a campus dormitory, ''how could Rick not know?''

In her first interview since the release of her book earlier this month, ''Breaking Cardinal Rules: Basketball and the Escort Queen,'' Powell says that the coach had to be aware of some of 22 shows she alleges that former staffer Andre McGee paid and took place from 2010-14.
