Lady Gaga has finished the first date of her huge world tour, thanking fans for coming out to see the Born This Way Ball via Twitter.
Gaga brought the elaborate stage show to Seoul, South Korea for the opening night and, according to her Tweets, everything went perfectly.
Tweeting before the show, Gaga said: "I can you hear you Korea. I'm shaking."
Then, after the show, she added: "I could barely sleep last night. It was the 2nd highest attendance of fans in the History of concerts in Korea."
"I'm so grateful for all of you, thank you monsters. Last night was like being completely prepared for a moment you could never prepare for."
However, younger fans of Gaga's were left out in the cold after the show was made strictly over-18 by the local government.
The Born This Way Ball hits Britain in September.
