Jessie J

On Monday, Jessie J performed in a church and made her reflect about her life.

The 25-year-old singer sang in an intimate showcase that made her think more of her life, and also accept her flaws and act more positive in this chaotic world.

'I stood still and closed my eyes and thought... I may make mistakes and let people down sometimes. I don't always get life right. I accept I have flaws as we all do and everyday I am trying to conquer them and be a hopeful and inspiring energy in this crazy world,' she wrote.

'I am always seeing where I can give more and be remembered as a courageous and admirable woman now and forever.' Jessie tries her best to be better in her work and accept the criticism, but she admitted it's not always easy. She said her intentions are pure and she only wants to put music into the world that makes others happy.

'My intentions are always to be light. Never dark,' she continued, thanking fans and signing off with a prayer. 'My heart is always leading me, learning and growing everyday. Thank you for believing in me and guiding me past the ones who try and bring dark into my life. I am so thankful for all that I have... #amen.'

Jessie performed in London's Hyde Park and Greenwich Park at the weekend, and will head on to Rio de Janeiro for a show on September 15.

She will then return to London for concerts on September 23 and 29 before embarking upon her Alive tour in Belfast on October 15.
