Single Tulisa can now focus on work

London: Singer Tulisa Contostavlos is happy being single and says she would now be able to concentrate more on her work.

The singer, who is currently seen as a judge and mentor on British version of "The X Factor", was in a relationship with N-Dubz singer Fazer for two years, which came to an end in March. The singer says she`s a free-bird and can now concentrate on giving her best on the show. "No man to stress about. I can just chill out and get on with my job," thesun.co.uk quoted her as saying. The 24-year-old was also in the news for the leaked sex tape with ex-boyfriend Justin Edwards. She had to go through a number of legal hearings to get the circulation of the tape banned. IANS
