The Waiting For Tonight singer scintillated in the cleavage-bearing clinging black dress which showed off her best assets.

The frock featured cut outs along the side and just under the chest in addition to a mesh detailing running down to side which no doubt accentuated her iconic backside.

She wore her highlighted brunette tresses down flowing over her shoulders as her skin looked flawless for being in her forties with natural, complimentary make-up on it.
