This is heartbreaking even though we don't really like Miss Allen!
A rep for the singer has confirmed the tragic news, saying, "It is with great sadness that we have to confirm that Lily Allen and Sam Cooper have lost their baby. 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, 25, was around six months pregnant.
This is the second time that the singer has suffered a miscarriage, after losing a baby in 2008 when dating Chemical Brothers star Ed Simons.
