If you thought Whitney Houston was high in that video from last week of her and Bobbi Kristina at the Prince concert [click here if you missed that] you were probably right...
From TMZ
According to our Prince sources, Whitney attended several Prince concerts in the last few weeks and appeared to be "intoxicated" at each show -- though our sources never saw Whitney drink alcohol or take drugs.
We're told Whitney was constantly badgering Prince's staff to let her up on the stage ... but Team Prince shot her down every time because P's people "didn't want her to embarrass herself."
Our sources say Whitney's erratic behavior, coupled with repeated and excessive ticket demands became too much for Prince -- and his team ultimately banned Houston from his concerts.
As TMZ first reported, Houston is receiving treatment in an out-patient rehab program for ongoing drug and alcohol problems.
