In a message on Twitter, Allen said she was still “very sick” but thanked her fans for their continued support.

On Monday, a spokesperson for the singer confirmed that she had suffered a miscarriage sixth months into her pregnancy.

“Thank you for all your kind messages,” Allen wrote on the social-networking website today (November 5).

“I'm still very sick but the messages are helping me to be stronger. Thank you x x.”

Allen and boyfriend Sam Cooper announced the singer's pregnancy in August.

It is the second time that Allen has suffered a miscarriage.

In January 2008, the star lost a baby with then-boyfriend, Ed Simons of The Chemical Brothers.

Allen and Cooper, 32, who owns a painting and decorating company, have been dating since July 2009.
