The Sheezus hitmaker lets loose backstage with half-naked video revealing her slimming secret

LILY Allen has never been one to take herself too seriously. But her latest posting to her Instagram account is likely to earn her some new fans, after she showed off her slimming secret – Spanx – in a hilarious topless video.

The Hard Out Here singer, who has been rocking a seriously hot body since relaunching her career earlier this year, danced to rapper Drake's Started From The Bottom last night, wearing just her Trust Your Thinstincts High Waisted Mid Thigh Shapers.
Covering her breasts with one arm and pulling some serious hip moves in the £74 pants, she sings along while filming herself in a mirror.

She tagged the video, "Cool mum. #drakespanxdance".
Lily, 29, who has children Ethel, three, and one-year-old Rose with husband Sam Cooper, has been promoting her new album Sheezus in Brussels.
The video comes just days after Lily showed off her nipples in a skimpy purple dress in Cannes.

Weight and body shape is clearly an issue that Lily is keen to talk about.
Earlier this year she clashed with Katie Hopkins after the former Apprentice motormounth said the singer was known best for "gaining two stone and looking pretty hideous" after having her children.
Lily also revealed that she gained 3st while carrying her children – weight that she has clearly worked very hard to lose.

Thanks for keeping it real, Lily!
