British singer Lily Allen has announced her comeback with a hard-hitting tweet and a new website.

The Smile hitmaker changed her Twitter address from her married name @lilyrosecooper back to @lilyallen on Friday (30Aug13), and launched an official website.

She then tweeted fans, "Hello, im Lily Allen, http://www.lilyallenmusic.com... and, I'm coming back, b**ches."

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

Earlier this month (Aug13), 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 (13).
