Madonna Adds Spine Doctor To Tour Needs 8/28/08

Madonna's massive touring entourage has just got bigger - she's added a top chiropractor to her party posse.

Dr. Steven Margolin has joined the 50-year-old singer on her Sticky and Sweet world tour, according to reports.

An insider tells America's Life & Style magazine, "It's (tour) going to be very draining, and she needs him around to aid her in her recovery time after each show."

"She'll have daily massages to relax her."

As WENN reported last week, Madonna's touring personnel includes 250 people.
