More than 30,000 fans of British-Irish boyband are waiting in anticipation for the group to start their set at the National Stadium, their first in Singapore.
The quintet, the most successful and popular boyband in the world right now, are scheduled to go onstage at 8pm.
While waiting, the crowd partied along to local DJ from Zouk, Lincey, who warmed them up with EDM tunes.
Among those here right now is Ms Azlizah Rosli, 21, who won a pair of VIP tickets courtesy of the ST170 Treats contest organised by The Straits Times.
The polytechnic student could not afford to buy tickets and had joined the contest after she found out about it on Twitter. She says: "When I received the email to tell me that I had won, I was stunned and speechless. I had to read five times to make sure that it was real."
Also in the crowd are 16-year-old twins Angela and Angeline Goh. The sisters, who are waiting to enter Polytechnic, received their tickets from their father, Mr Boon Beng Goh, 52, who took part in the ST170 Treats contest.
Says Angela: "I'm really excited right now, we have been listening to them since we were Secondary Two. I hope they play the song Steal My Girl, it's really catchy and I will sing along if they do."
