Chaka Khan — Soul Legend In Drug Rehab At 63 Years Old

Chaka Khan is going into rehab — as the legendary soul singer fears she'll die like Prince! The "Tell Me Something Good" diva added that her sister would be joining her in entering a drug rehab program to beat their addictions. Chaka said in a statement: "The tragic death of Prince has had us both rethinking and reevaluating our lives and priorities. We knew it was time to take action to save our lives. My sister and I would like to thank everyone for their support, love and prayers."

The former "Dancing With the Stars" contestant had a huge hit with Prince's song "I Feel For You," but some fans were already planning to skip this summer's shows. The troubled singer's drug problems weren't a secret to the many audiences that she left disappointed after live shows this year!

"Her concert started around 20 minutes late," said one angry former fan. "She only sang a few songs — not even completely — and then she left the stage for about 20 minutes! Next thing we knew, the show was over!"

Said another audience member who caught Chaka in concert: "She came onstage and was off-key from the beginning. I thought it was just a note or two, but it was for the entire show. When it was time for the high notes she screamed the words...She screeched through 3 songs and then said 'I'll be right back, I promise!" Well, 15 minutes later of listening to the stage band, she didn't return!"

Chaka's representatives are saying that the R&B star will be back on tour in August — but she'll have to see if there's a crowd ready to give her a second chance.

Said one longtime fan: "Chaka's voice was in a lot better shape in 2015, so things seem to have only really gotten bad for her this year. Maybe she'll get her voice back — and at least she won't keep stopping the show to get more drugs!"
