"Lily Allen is back in hospital, where she is being treated for septicaemia," her rep told U.K. publication the Daily Mail on Saturday (November 6) "She is responding well to treatment and her condition continues to improve."
Septicaemia also known as Septicemia, is 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.
The condition has occurred just days after the singer confirmed she had suffered a second miscarriage after losing a child in 2008.
"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 Monday, according to People.com. "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."
Allen and Cooper, who owns a building company, have been dating since July 2009. The couple announced the pregnancy in August after getting the all-clear from her doctor following her first trimester. The pair was expecting a son.
Unfortunately, this is not the first time Allen has endured a miscarriage. The singer lost her first child with her then boyfriend, Ed Simons of The Chemical Brothers, two years ago.
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.
