Leona Lewis betrayed many times

London: Singer Leona Lewis says she has met some mean people ever since she shot to fame with ‘The X Factor’ in 2008 and this has hampered her trust. "I`ve met some deplorable people over the past six years who have done some really bad things and I`ve seen their betrayal of my trust unfold before my eyes," theindependent.co.uk quoted her as saying. However, the 27-year-old has learnt from her past mistakes. "It was hell but I`ve learnt from it and I`m much better at knowing who I should avoid," she said. IANS
