The man who punched Leona Lewis during a book signing in London (details and photos here) was identified as Peter Kowalczyk, a 29 year-old aspiring singer who had auditioned and been rejected on the British talent show ‘The X Factor’ won by Leona back in 2006.

Peter was charged with assault and has been sectioned under the Mental Health Act. The 24 year-old ‘Bleeding Love’ singer was forced to cancel a promotional visit to Germany but promised she would soon start rehearsing for her upcoming UK tour that kicks off in London next month.
