madonnaMadonna’s celebrity friends shouldn’t expect any freebie tickets to the star’s forthcoming Sticky & Sweet Tour - she’d rather they paid their own way.

A source told OK magazine: “She’s a businesswoman and sees her shows as work, not a party for all of her friends.

“She doesn’t think having celebrities in the front seats makes her cool.”

Tickets for the singer’s UK tour dates run from £65 to £160. The tour kicks off in Cardiff next Saturday and after a tour of mainland Europe, returns to London in September. Madonna turns 50 today.
