Madonna has reportedly added a spine specialist to her 'Sticky & Sweet' tour entourage.
The singer's world jaunt allegedly includes a team of 250 staff.
Chiropractor Dr Steven Margolin is the latest person to join the touring party, according to Life & Style magazine.
"[The tour] is going to be very draining, and she needs him around to aid her in her recovery time after each show," said a source.
"She'll have daily massages to relax her."
The 'Sticky & Sweet' tour began at the Millennium Stadium in Cardiff on Saturday.
