Lily Allen is being treated at a London clinic for depression.
The 22-year-old singer was heartbroken after suffering a miscarriage in January and then splitting from the father, Chemical Brothers star Ed Simons, and has now decided to seek professional help at a top facility.
A friend told Britain’s The Sun newspaper: "The last couple of months have been really hard for Lily. She was so happy to be pregnant and was willing to give up her showbiz life to settle down and have a family.
"Her miscarriage was a huge blow and she hasn't really recovered. She has tried to put on a brave face but she found she needed to get some profession help."
Lily, who recently admitted she feels "sad and lonely", is said to be slowly coming out of her black hole thanks to the treatment. The pal added: "She is responding well and is pleased she is being allowed to film her TV chat show 'Lily Allen and Friends' and to keep in touch with the friends supporting her."
Meanwhile, on Monday night (03.03.08) Lily was horrified to find the windows of her new BMW had been smashed while she was at London's Groucho private members club.
The 'Smile' star is adamant paparazzi caused the damage. She wrote on her blog: "It was one of the many paparazzi who were following us who did it. It was a scary situation and I want people to know that it was totally their fault and that the whole situation has angered and upset me." |
