The four-piece have come a long way since winning the X Factor in 2011, selling seven million records and enjoying success, not only in the UK and Ireland, but also Japan, Australia and the US.
In 2013, around 2,500 people saw the band perform at the Waterfront Hall.
But last night, there were 10,000 fans - known as 'Mixers' - packed into the arena for the hotly-anticipated concert.
The quartet's Get Weird Tour was due to kick off in Belfast with concerts at the end of last month.
But there were tears and tantrums on the day of the gig when they cancelled the performance less than an hour before the first show was expected to start, as Jesy had taken ill. Those gigs have now been rescheduled for July 2.
The girls said they were very pleased to be performing in Belfast. Perrie treated us to her impersonation of Nadine Coyle's Derry accent and Jesy told everyone to always be themselves and be confident.
Pyrotechnics, sparkly costumes, sexy dancing, big screens, flashing lights, lasers and positive messages were the order of the day as we were treated to a selection of tracks from the DNA, Salute and Get Weird albums.
The girls belted out Change Your Life, A.D.I.D.A.S, Secret Love Song, OMG, Move, the incredibly catchy Wings and chart topping hit Black Magic.
I am not quite the group's target demographic, and despite enjoying myself much more than I thought I was going to, my favourite little mix still remains tonic water with gin.
But for the thousands of dedicated young fans in the audience, the girls reign supreme, particularly - in the opinion of my 'plus one', nephew Ethan - Jade, as "she's the best singer".
There is usually a weak link in pop groups but in fairness to the four they all sounded very good and put on an energy packed two hours of entertainment.
It was Ethan's first gig and he gave the show five out of five. He reckons the Mixers with tickets for the rescheduled shows in July are going to enjoy the big, loud, fun party.
