We all need a little bit of help sometimes and Lily Allen is no exception. Lily Allen shared her love for Spanx with the world by posting a video on Instagram of her dancing in her dressing room in a pair of Spanx. Later that evening she stunned the crowd in Brussels in a metallic cut out dress, proving that Spanx is the not-so-secret wardrobe essential for women.

Lily is wearing the Trust Your Thinstincts High Waisted Mid-Thigh Shaper, available from spanx.co.uk for £74.
