Lady Gaga appeared to collapse on stage during the opening show of the New Zealand leg of her Monster Ball tour at the weekend.

During 'Bad Romance', Gaga is said to have wobbled on her feet and hit the ground seemingly exhausted.

According to the Daily Telegraph, the 23-year-old was forced to sing the rest of the track while lying on the floor to the bemusement of the crowd.

Several reports claim that Gaga is suffering from exhaustion due to her increasingly hectic schedule.

In the past two weeks, Gaga has jetted between the UK, New York, Los Angeles and now New Zealand and Australia.

In January, Lady Gaga collapsed shortly before she was due to play a gig at Purdue University in Indiana.

Her publicist said at the time: “Due to exhaustion and dehydration, Lady Gaga collapsed and passed out before her show tonight in West Lafayette, Indiana.

“Her physician has advised her to take a few days off to rest.”
