The low-cut garment featured thin straps and a faux lace trim along the bust, which matched the below-the-knee hemline.

The bodycon garment clung to Lauren's every curve and highlighted her fantastic figure.

Lauren - who raises two-year-old Eric with the music mogul, and Adam, nine, is from her previous marriage to businessman Andrew Silverman - completed her look with some choice jewellery pieces and a black clutch bag.
