Gaga was suffering from jet lag
Lady Gaga has blamed jet lag for causing her to collapse on stage in New Zealand.
The eccentric pop superstar revealed all in an interview on an Australian radio show, according to People.com.
"I was so jet lagged, 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 because I was going to pass out," she told Kyle and Jackie O.
It's not the first time Gaga's packed schedule has caused problems - at the start of this year the chart-topper had to cancel several shows, citing exhaustion as the reason.
She may be tired, but the Telephone singer seems to be enjoying her trip Down Under.
She tweeted on Tuesday: "Writing music, leopard tights... I'm grateful to have fans that continue to inspire me. Ready to sweat tonight Melbourne."
