And it seems Kim is using her former bikini body as motivation to get back in shape.

In a Snapchat she shared during her fitness session, the mother-of-two circled a racy poster of herself reclining in a gold bikini.

She added the caption 'I miss you!' just below the image of her bronzed physique lying down in a sexy pose.

Kim kept a low profile as she left her gym, hiding behind large black sunglasses and wearing her hair up in a ponytail.

The E! reality star also bragged about her fame and fortune in the posts which had fans suspicious that Kanye had seized control of her account.
