"I had a dream when I was a little girl and it was to have an arena tour," she told her fans - "Heartbeats" - later in the evening. It is hard to believe that it has taken this long for her to head out on a tour of this size given that her breakout hit 'Do It Like A Dude' was released back in November 2010. However, she works the 15,000 strong crowd with ease and proves that she is more than up to the task of filling the arena with her powerhouse vocals and bags of stage presence.
For the most part, the material from her latest record translated well on stage, with tracks like 'Sexy Lady' and 'Excuse My Rude' proving to be crowd-pleasers despite only being released a few weeks ago. Jessie J may be a divisive artist in today's pop scene but the strength of her vocals cannot be denied. A performance of 'Who You Are' offered the best example of her strengths, accompanied by a simple backdrop of family videos of the star in her youth. Her skill shone through again on 'Do It Like A Dude', which was mixed with Jay Z and Kanye West's 'Ni**as in Paris' with superb results.
Despite the focus on Jessie's voice, it didn't come at the expense of a visually pleasing production. The show was divided into five distinct sections: Awake, Love, Instinct, Value and Energy. The interludes saw the singer in a variety of different costumes as the crowd listened to poetry that she penned herself.
The sentimental messages of 'love who you are' and 'live life to the full' may have been overused during the 90-minute show but it is only a small complaint in what was a momentous night in Jessie J's career. "This is a huge moment for me", she told the crowd towards the end of the evening, and it is likely to be the start of many more momentous occasions for the London-born songstress.
