The NDubz singer from North London is dressed as Tallulah from the musical Bugsy Malone aged 11.
Tulisa shared the adorable #tbt snap on her Instagram page with the caption; 'My name is Tulisaaaaa'. With nearly 5000 likes, clearly her fans loved the private photo.
Tulisa, 27, was most recently a judge on The X Factor alongside music mogul Simon Cowell between 2011-2012, and helped bring pop group Little Mix to fame.
We don't think Tulisa has changed very much over the years - what do you think?
