This is just NOT Whitney Houston‘s week! After entering an outpatient rehab program for drug and alcohol issues, TMZ is now reporting that the legendary icon will no longer be allowed to see any future shows for another legendary icon … Prince!

Reps for Prince have reportedly become so fed up with Houston’s erratic behavior and constant ticket demands that she is no longer allowed at any of the “Purple One’s” concerts.

Houston attended several Prince concerts in the last few weeks and appeared to be “intoxicated” at each show, sources say. She was reportedly badgering Prince’s staff to let her up on the stage, but was not allowed.

SMH … first Charlie Sheen, now Whitney. (Deep sigh) Cocaine is one hell of a drug!
