Lily Allen's pet dog has been kidnapped in London.

The English Bull Terrier was snatched last Wednesday whilst in the care of the singer's friend. It was in a van in East London, when the perpetrators struck.

The singer has pleaded for the return of the pet via her blog, adding that the dog requires imminent medical treatment.

"Not only am I devastated my dog has been taken, I am concerned for her well-being as she needs an operation on her stomach and is having medical treatment," she wrote. "There is a reward on offer. Please, anyone, help me find Maggie. No one will be angry — me and my family just want Maggie home. I love her so very much.”
