The 22-year-old star put on a very busty display as she attended the launch of Madison White Forest’s winter Terrace which was sponsored by CîROC Vodka.

Demi opted for a floor-length black dress which featured velvet panels and lots of sheer material.

The garment’s plunging neckline left very little to the imagination and also featured a thigh-high split.

Perhaps feeling the winter weather later on, Kimberley covered up in a khaki duster coat as she headed home in black taxi.

The former reality star later posted a snap of herself at the rooftop bar with St Pauls in the background and simply captioned it: “beautiful london.”
