5. Lady Gaga
Lady Gaga performed a massive 201 shows across the world as part of her 'Monster Ball' tour between 2009 and 2010 but rather than taking a well deserved break the Mother Monster is already preparing to embark on a new world tour with the 'Born This Way' Ball later this month! The tour will promote Lady Gaga's 2011 album 'Born This Way', which has already spawned five hugely successful singles, and the 'Marry The Night' singer and is believed to be aiming to break U2's record for the highest-grossing and most attended world tour ever!
