After being hospitalized for a blood infection last week, Lily Allen's condition is improving, according to People.com. Additionally, sources say that letters fans have been sending the British pop chanteuse have helped boost her spirits.

"Lily thanks everyone for their messages of support and again asks that she and partner Sam Cooper be left alone whilst she recovers," her rep Murray Chalmers said in a statement about the pop star. News of the singer's hospitalization broke on Saturday. She has septicaemia, a dangerous infection characterized by the presence of bacteria in the blood. It can be brought on by other infections in the body, such as conditions in the abdomen, lungs and urinary tract.

"Lily Allen is back in hospital, where she is being treated for septicaemia," her rep had said on Saturday. "She is responding well to treatment and her condition continues to improve."

On Friday, the singer expressed her gratitude for all the well wishes she had been receiving from fans during this difficult time. "Thank you for all your kind messages," Allen tweeted.

Earlier this month, news broke that Allen had suffered a miscarriage. It was the singer's second.

"It is with great sadness that we have to confirm that Lily Allen and Sam Cooper have lost their baby," her rep Murray Chalmers said at the time. "The couple ask that their privacy be respected and that they be left alone at this deeply distressing time. No further comment will be made."
