And despite having just spent 18 months touring the globe, the Judas singer has revealed that she is keen to embark on another “marathon” tour in 2012.
Gaga, real name Stefani Germanotta, told MTV News: 'I do have plans, it will be at the top of next year, but I have to begin rehearsing by the end of this year. That's what I do. It's time for another marathon.'
The 25-year-old star added: 'If you're running a marathon, and you're about to cross the finish line, you don't stop and say, 'Oh, once I cross it, it's over'. You run as fast as you can to get there as quickly as you can.'
