Belfast-bound Lady Gaga wowed her little monsters in a dazzling performance at Dublin's O2 arena and was keen to stress that she sings live.
Fans got into the groove by dressing up in flamboyant outfits as a tribute to the eccentric singer.
However, she disappointed fans by failing to meet them off stage as she asked for constant security from 12 body guards who kept the public at bay.
The peroxide blonde ended up arriving at the Four Seasons Hotel in Ballsbridge with only a few hours to spare before her first Monster Ball gig in Dublin.
The talented New Yorker did not let the short amount of preparation destabilise her, giving a memorable performance that showed no signs of strain or stress.
The off-the-wall singer played for over an hour and a half, in front of 14,000 fans.
She made a point of telling her detractors that her acclaimed performance was all live.
"I don't f*****g lip-synch!" she told the crowd.
And while she may be a superstar, the singer proved she could rough it like the best of us by travelling to Ireland by humble ferry.
The exuberant 24-year-old arrived just in time for her Dublin gigs, which kicked off on Tuesday night, after catching the ferry in Wales on her tour bus.
The wacky performer caused mayhem shortly after leaving London when she asked her staff to get her some food, forcing the bus to park on the side of the A40 for 40 minutes.
Lady Gaga then had to sit in the lay-by with her minders when she finally got her hands on some fish and chips.
She sang her most famous hits Telephone, Just Dance and Poker Face to the delight of her jubilant audience, who were also greeted by a giant monster on stage. However, fans who were hoping to greet her backstage did not get a chance to congratulate her on her sell-out gig.
Lady Gaga, who has sold over 43 million albums worldwide, requested 24-hour protection to keep potentially extreme fans at bay.
"She takes no chances when it comes to security and likes to feel protected at all times," an insider revealed. "Some fans are a bit over the top and send her lots of violent messages which have scared her in the past."
It is understood that the popstar will be spending most of the day in her exclusive suite, probably unwinding by doing some yoga or Pilates, as suggested by the requests she made to the Four Seasons.
"The hotel had a call from one of her assistants on Friday with a number of requests," an insider said.
"They had a small number of special requests including that a bikram yoga and Pilates expert be available round the clock, as apparently she sometimes likes to wind down by working out after a show."
"They also asked for a constant supply of fresh fruit and bottles of water at room temperature," the insider added.
The New York-born performer heads to Belfast this weekend for a three-night stint at the Odyssey Arena.
