Whilst, the 'Material Girl' hitmaker has been living in Lisbon, Portugal after her son David, 12, joined football team Benfica FC's youth academy, she said she was eager to get working on the production for a new run of dates for next year.

The 'Hung Up' singer was on 'Live With Kelly & Ryan' where she took part in a game of Sketching With The Stars, alongside her friend Anderson Cooper who asked her about her touring future.

On when she plans on hitting the road again, Madonna told Anderson: ''Soon. I gotta get my show together. 2017 was soccer mom in Portugal. 2018 ... I'm coming back, baby. I'm coming for you!''

Madonna's last extensive run was her 2016 'Rebel Heart World Tour', which concluded in Sydney, Australia on March 20.
