MUMBAI: Pop star Madonna is planning a world tour in 2015 that will be like nothing she has done before.

She wants to mark 30 years since her groundbreaking "Like a Virgin" concert series from 1985 with a string of shows across the globe in support of a planned new album.

"This is going to be one very special tour. Madonna wants to pull out all the stops, especially because it is 30 years since the 'Virgin' tour," femalefirst.co.uk quoted a source as saying.

"Like her 2012 'MDNA' tour, where she played 88 dates in places including Europe, South America and Asia, Madge will be ­travelling the world. Once the new record is finished she can concentrate on the concerts," the source added.

Despite already having nine huge tours under her belt, the 56-year-old singer wants to "push boundaries" and offer something new with her 2015 gigs.
