Just when it seemed like Whitney Houston might be getting her life back in order … well. This time Houston has managed to get herself banned from all current and future Prince concerts.

Although Houston was not seen drinking or taking drugs, sources reported that she still appeared to be “intoxicated” at a few recent performances. Apparently, Houston demanded concert tickets and badgered Prince’s staff to let her on stage when she attended the shows. The staff refused to let her because they “didn’t want her to embarrass herself,” reports TMZ.

She has been undergoing treatment for her addiction to drugs and alcohol since she checked herself into an out-patient rehab program in April.
