She wrote: ''I'm so excited to be opening up my world to you on TraceMe. You guys know that I tend to be private with a lot of things, but with TraceMe I can have a genuine, unfiltered connection with you all.

''My motivation for this was to give back for all of your support throughout the years. We now have a special place where you can get to know more about me, and see all the fun things that go on with my music, my family, my fashion and so much more.''

Some of the pictures were also shared on Instagram, where the 'I Bet' singer urged fans to check out the full set on TraceMe.
