Lady GaGa took her concert to Philadelphia, Pennyslvannia last night in her true GaGa fashion.   She recently almost collapsed on stage during a performance in Georgia and has been ordered to take a month off of work.  A source told The Sun:

“Stefani has been working relentlessly since last summer. She has criss-crossed the globe on numerous occasions promoting her album… and the pressure has now started to get to her.

“At a recent show in Atlanta she nearly collapsed on stage the day after a particularly wild night out. Her management have spotted the warning signs and do not want her going off the rails.

“They’ve scrapped all her commitments in August to give her time to get her head straight.”
