But the Bad Romance songstress was left stunned by an unexpected mishap while in the middle of her hit song Judas at Sunday's show in New Zealand.

Ouch: Lady Gaga was accidentally hit on the head by one of her backing dancers during her concert in Auckland, New Zealand today

The 26-year-old had been dancing attached to the pole by a rope but later left the podium and ducked down to pick up a prop gun.

Her backing dancer then immediately picked the pole up and was turning it from its vertical position to carry it off horizontally.

It was at this moment that as Gaga raised her head, the pole came crashing down on her.

She immediately carried on but later mentioned the incident to the audience.

'I want to apologise,' she told fans according to TMZ. 'I did hit my head and I think I may have concussion. But don't you worry, I will finish this show.'

Gaga is playing three concerts at the Vector Arena.

During the shows she, unsurprisingly, underwent numerous costume changes.

She also appeared as a hologram and later thanked a 78-year-old male fan for turning up, telling him 'you're lovely.'

During the two-hour sellout show she also played guitar, rode a motorbike and fell into a 'meat grinder.'

She also appeared onstage riding what resembled a giant louse.

The flamboyant singer made for a bright sight as she arrived in Auckland last week clad in a neon orange dress.

The singer got a lively welcome from crowds of fans packed outside her hotel.

Her appearance came amid reports the 26-year-old singer has rekindled her romance with Vampire Diaries actor Taylor Kinney.

The songstress sparked rumours of a reunion after she was joined by the 30-year-old actor in Thailand and then continued on to Singapore with her.

A source told Us Weekly: 'They sure looked like they were back together - holding hands and being cute everywhere they went. They were seen kissing right as they got into the [hotel] elevator.'

The insider confirmed that they were dating once again back on and trying to make things work despite her demanding lifestyle.

They said: 'They are going to try and make it work even with her crazy schedule. Gaga realised she missed him.'

Taylor and Gaga initially split in early May after ten months together. At the time, sources said the Grammy winner's hectic calendar was to blame.

The informant explained: 'She will be touring nonstop until next year. There's just no room for anything else. Her work is all-consuming.'

A a second source admitted last month that things between her and the screen star were still complicated.

'They may still be trying to make it work. She feels like having him keeps her grounded. Obviously she thinks he's hot... She says he's 'really cool.'
