The 24-year-old singer performed last night at London’s Hackney Empire theatre.
Lewis, who was an X Factor winner, was attacked by a fan at a book signing last month. While sitting in a bookstore to autograph copies of her book, a frustrated fan who wanted to compete on X Factor hit Lewis on the side of the head. Following the incident, the English singer canceled all of her scheduled performances.
At last night’s performance, Lewis told the crowd, "I just want to say thank you so much for coming to support me."
The man who attacked Lewis, Peter Kowalczyk, 29, had his case adjourned on October 27. He has been in the care of the Lambeth Hospital mental care ward, where he is undergoing evaluations. He is expected to return to court on November 23.
