Lily Allen receiving treatment for depression

Pint-sized pop princess Lily Allen is receiving treatment for severe depression, it has been claimed.

The singer -- who is seeking the treatment at a top private clinic -- hit rock bottom after suffering a miscarriage in January -- and splitting with the baby's father, Chemical Brothers star Ed Simons shortly after.

The heartbroken star, 22, is reportedly being treated at a residential clinic, but is allowed out to see pals and to film her BBC3 chat show, Lily Allen and Friends.

A source close to Lily said last night: "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 professional help."

Lily recently canceled her performance at the Isle of Wight Festival in June, and is also likely to delay the release date for her forthcoming second album.

The source added to British newspaper The Sun: "She really believed she and Ed were perfect together so she was devastated when they broke up.

"But she is responding well to treatment and is pleased that she is being allowed out to film her TV show and to keep in touch with the friends supporting her."
