Pop star Lily Allen in hospital with blood poisoning

Lily Allen suffered a miscarriage earlier this week

Pop star Lily Allen is in hospital with blood poisoning just days after suffering a second miscarriage, her spokesman has confirmed.

Allen, 25, is being treated for septicaemia, and thanked fans for their messages of support.

She was around six months pregnant when she lost her baby earlier this week.

"She is responding well to treatment and her condition continues to improve," her publicist said in a statement.

"Lily thanks everyone for their messages of support and again asks that she and partner Sam Cooper be left alone whilst she recovers."

On Sunday the singer's publicist said he had nothing to add to that earlier statement.

Twitter message

Allen had indicated she was unwell to fans on her Twitter site on Friday, tweeting: "I'm still very sick but the messages are helping me to be stronger. Thank you xx."

Friends of the star, who previously had a miscarriage when she was dating Chemical Brothers star Ed Simons in 2008, sent messages of support to the singer.

Myleene Klass tweeted: "Lily Allen and her partner Sam. I am so truly sorry and sad for you both and your family."

Emma Bunton wrote: "Thinking of Lily Allen and her partner at this very sad time. Sending them lots of love."

Fashion week

Allen started dating 32-year-old Cooper, a builder, last year.

She had started to wind down her music career in recent months and set up a vintage clothing business Lucy In Disguise with her sister Sarah Owen.

She performed at the Wireless festival in London in July and was photographed at Paris fashion week last month.

The star announced she was pregnant in August after being given the all-clear at her three-month scan.

She has released two best-selling albums - Alright, Still and It's Not Me, It's You - and has had a number of hit singles including The Fear and Smile.
