Lily Allen made her live return at Paris Fashion Week yesterday (26.02.13).

The singer made her first public performance in four years at the Girls Only! Etam Lingerie show - directed by Mark Ronson - singing her track 'Smile', her debut single, from 2006.

Before her performance she tweeted: ''Just did rehearsal for tomorrow's ETAM Show with @iamMarkRonson, still know the words to Smile, which is good. #mumback (sic).''

Lily - who now goes by the name Lily Rose Cooper - was watched in the audience by her husband Sam Cooper and their two-month-old daughter Marnie.

Lily, 27, officially retired from music in 2009 but returned to the recording studio last year. She has only sung live once since then, performing a duet of 'True Love', a track she recorded with Pink, at a secret show at Sony Studios last August.

Lily and Sam also have another daughter, 15-month-old Ethel, and she has said she is ''definitely'' writing about motherhood on her comeback album.

However, she also said fans may face a wait to hear new music, saying: ''It's great to work at my own pace, with no commitments other than to make music. I'm excited to be heading back into the studio.''

Also performing at the Etam Lingerie show, held at the Bourse de Commerce, were Rita Ora, M.I.A., Selah Sue and Lykke Li.
