The Fear singer Lily Allen has announced her music comeback on social networking site Twitter.

The 28-year-old singer changed her Twitter address from her married name @lilyrosecooper back to @lilyallen yesterday (August 30), and launched an official website.

Taking to her Twitter page, she wrote: "Hello, im Lily Allen, and, I'm coming back, *******. [sic]"

The website includes links to a selection of her videos and an option for fans to sign up for a newsletter.

Earlier this month, Allen hinted she was ready to release a comeback single after working with producer Greg Kurstin, who contributed to her 2009 album It's Not Me, It's You.

The singer took time off to become a mother - her second child was born in January.
