Houston recently enrolled in an outpatient rehabilitation program to seek treatment for substance abuse issues. She was subsequently hit by rumors that she had been banned from future Prince shows after allegedly behaving bizarrely at two concerts in Los Angeles this year, but a representative for Prince says this isn't true.
The spokesperson, in a statement released to Drfunkenberry.com, also confirmed that Prince was delighted to invite Houston onstage during one of his recent gigs: "Whitney Houston is always welcome at Prince shows 4 all of eternity. Seeing her at 2 shows at The Forum in L.A. was a treat, especially when she sang with Chaka Khan and danced with Prince during his set. We love her always."
