Bieber fever has swept the city centre as thousands of giddy fans queued for more than 24 hours to see their hero.
The 19-year-old pop star has taken his world tour to the Capital FM Arena, where enthusiastic – bordering-on-hysterical -girls waited for his arrival.
It's not every week Justin Bieber visits Nottingham so his committed army of fans were not going to miss the chance to soak up the opportunity to see their heartthrob.
Gemma Collins, 14, who lives in St Anns, said: "This is my first Justin Bieber concert and I'm so excited.
"It's just amazing to be here I've met so many other fans, it so amazing. He's my idol and I just love him."
The teen titan celebrated his 19th birthday on Friday making the occasion extra special for the city's very own fans, known as 'Beliebers'.
They started queuing at 2pm on Friday with the doors to the concert opening at 6.30pm the following day.
Emma Greeson, 21, lives in Bennett Street, Long Eaton, said:
"I started queuing at 3.30pm on Friday and we were getting emotional over the fact he was turning 19, so we celebrate by doing the Harlem Shake.
"It was so cold staying here over night but it was worth it because I'm doing it for Justin. I've got butterflies in my stomach and I'll probably cry when it's time for him to come on."
Negeen Rogers, 14, from West Bridgeford, said: "I'm extremely excited. I've cried five times already, I've chase the four tour buses that have passed."
Hayley Broadhead, 16, from Worksop, said: "This is the best ever situation to be in. I've been waiting for this ever since the tour began.
"It's a privilege to come because Justin Bieber is my favourite singer."
Kayleigh Jansen, 16, who lives in Doncaster, was the first in the queue, she said:
"I've been camping in line since 2pm on Friday. The last time I was here I sat right at the back, in the very worst seats but now I'm going to be standing right at the front with the best view.
"I'm going to tell him that I love him."Click here to view a picture gallery of the fans.
