Cheryl reunited with band mates Kimberley and Nicola for the launch of her collaboration with haute jeweller de Grisogono at Nobu.

Ms Cole has turned her hand to jewellery design with her Promise ring, which features rose gold and blackened silver, cut to spell the word "promise" and intended to be worn on the little finger. If you fancy blinging up you fingers, it'll set you back around €920.

The launch party marked Cheryl's first public engagement since her illness, and we're pleased to report that she looked on form in her gold embellished Elie Saab frock. Kimberley wore an figure-hugging LBD and Nicola opted for unusual sequinned and sheer dress, but fellow Girls Aloud members Sarah and Nadine did not make it to the party - further fuelling rumours of a feud between the girls.
