AceShowbiz - Singer/songwriter Ryan Tedder has warned Lady GaGa to take a break from her grueling tour schedule after his pop pal "passed out" on stage three times during a recent concert in New Zealand. GaGa sparked fears for her health after fan video footage from her show in Auckland in early March showed her looking fatigued, before lying down on stage during her performance of the song "Bad Romance".

A promoter for her Monster Ball trek claimed the singer was feeling "tired and dehydrated", but GaGa later revealed she suffered a series of blackouts during the gig. She said, "I was so jet lagged, I got in the night before and the jet lag just really caught up with me. I passed out about three times on stage that night but I got myself to the floor. I'd rather die on stage than walk off the stage because I was going to pass out... It's never happened to me before, I was just really tired."

But OneRepublic's frontman Tedder fears GaGa will wear herself out if she continues to push herself to the limit. He tells People magazine, "GaGa has to be careful. She's already larger than life. How do you get larger than that?"
