The singer, who has taken time out in recent years to have babies, performed live at the ETAM show at Paris Fashion Week.

And while she covered up her post-baby weight-loss in a floaty patterned dress, she was joined by a load of ladies who had far less on.

Mrs Cooper shared the stage with a bunch of half-naked underwear models, who strutted their stuff whilst Lily sang.

And the mum-of-two took a gander at the skinny bunch, as they strutted past her during her first gig in four years.

Earlier Lils took to Twitter to tease followers about her return to the stage, posting: "Just did rehearsal for tomorrow's ETAMShow with @iammarkronson, still know the words to Smile, which is good #mumback

And her two-month-old baby daughter Marnie was in the audience to cheer on her popstar mum, joined by daddy Sam Cooper.

Lily was also joined on stage at the swanky fashion show by British popstar Rita Ora, who sexed up the stage in a short, lace 60s-style dress with strappy gladiator heels.
