Leona Lewis wants to quit showbiz.

The 24-year-old 'Bleeding Love' singer - who shot to fame after winning the 2006 series of UK TV talent show 'The X Factor' - is reportedly considering abandoning her celebrity lifestyle in Los Angeles to live a "normal" life in London with her boyfriend Lou Al-Chamaa.

An insider said: "Career-wise, Leona's dreams have come true. But she doesn't really seem to socialise in Los Angeles because she misses Lou so much. I think she wasn't quite aware how different her life would become.

"Leona is torn because she loves being a singer but Lou is the love of her life. Sometimes I think she would like to fly back to London and never go to another red-carpet event again.

"I guess Leona would be happier eating a home-cooked meal with Lou in rainy old London than she'll ever be in the glitzy bars in Los Angeles."

Leona and Lou are unlikely to be reunited any time soon, with the singer set to embark on a 14-month world tour when she finishes her second album later this year.

The source added: "Lou and Leona look at other couples who manage to keep their relationship alive even though they sometimes live apart. They know they're a strong enough couple to make it work."
